-            all file dates are real. at least as real as i could figure out. when i moved data across drives over my
-            years, i accidentally had a few points where i stamped over all the dates with the day that moved the files.

-            it was all stored though, but jeez what a nerd.
-          </p>
-          <p>
-            a few files were touched up for privacy, or otherwise re-encoded. some of them i added extra metadata.

-          <p>
-            from the bottom of my heart: i hope you enjoy. it has been a nightmare putting this all together.

-        <p>today is my 21st birthday. april 30th, 2025.</p>
-        <p>it's been nearly six months starting hormones.</p>
-        <p>sometimes i feel great,</p>
-        <p>sometimes i get dysphoria.</p>
-        <p>with the walls around me gone</p>
-        <p>that shit hits way harder than it did before.</p>
-        <p>ugh..</p>
-        <p>i'm glad the pain i felt is now explained,</p>
-        <p>but now rendered in high definition.</p>
-        <p>the smallest strands of hair on my face and belly act</p>
-        <p>as sharpened nails to pierce my soul.</p>
-        <p></p>
-        <p>it's all a pathway to better days; the sun had risen.</p>
-        <p>one little step at a time for both of us.</p>
-        <p>today i quit my job. free falling, it feels so weird.</p>
-        <p>like sky diving.</p>
-        <p>the only thing i feel is cold wind.</p>
-        <p>the only thing i see is everything,</p>
-        <p>and it's beautiful.</p>
-        <p>i have a month of falling before the parachute activates,</p>
-        <p>gonna spend as much time of it on art as i can.</p>
-        <p>that was, after all, my life plan:</p>
-        <p>i wanted to make art, all the time,</p>
-        <p>for everyone.</p>
-        <p></p>
-        <p>then you see what happened</p>
-        <p>to the world and the internet.</p>
-        <p>i never really got to live through that golden age,</p>
-        <p>it probably sucked back then too.</p>
-        <p>but now the big sites definitely stopped being fun.</p>
-        <p>they slide their cold hands up my body</p>
-        <p>and feel me around. it's unwelcoming, and</p>
-        <p>inconsiderate to how sensitive my skin is.</p>
-        <p>i'm so fucking glad i broke up with YouTube</p>
-        <p>and their devilish friends.</p>
-        <p>my NAS is at 5 / 24 TB</p>
-        <p>and probably wont fill for the next decade.</p>
-        <p></p>
-        <p>it took 2 months for me to notice my body changed.</p>
-        <p>that day was really nice, but it hurt a lot.</p>
-        <p>a sharp, satisfying pain in my chest gave me life.</p>
-        <p>learned new instincts for my arms</p>
-        <p>so they'd stop poking my new shape.</p>
-        <p>when i look at my face</p>
-        <p>it's like a different person.</p>
-        <p>she was the same as before, but completely new.</p>
-        <p>something changed</p>
-        <p>or i'm now used to seeing what makes me smile.</p>
-        <p>regardless, whatever i see in the mirror, i smile.</p>
-        <p>and, i don't hear that old name much anymore</p>
-        <p>aside from nightmares. and you'll never repeat it, ok?</p>
-        <p>okay.</p>
-        <p></p>
-        <p>been playing 'new canaan' by 'bill wurtz' on loop</p>
-        <p>in the background.</p>
-        <p>it kinda just feels right.</p>
-        <p>especially when that verse near the end comes on.</p>
-        <p></p>
-        <p>more people have been allowed to visit me.</p>
-        <p>my apartment used to be just for me,</p>
-        <p>but the more i felt like a person</p>

-          <p>journal - 2024-09-14</p>
-          <p>
-            been at HackMIT today on behalf of the company. it's fun. me and zack were running around looking for people
-            that might be good hires. he had this magic arbitrary criteria to tell "oh this person is probably cracked
-            let's talk to them" and we go to the first one. they were a nerd, perfect. they seemed to be extremely
-            talented with some extreme software projects.<br />
-            okay.. oof... its still clouding my mind<br />
-            i cant shake that feeling away
-          </p>
-          <p>hold on...</p>
-          <p>
-            at some point they open one of their profiles to navigate to some code, and it displays for a couple of
-            seconds: "pronouns: she/they". i don't actually know anything about this person, but it was my perception
-            that she is trans. their appearance, physique, and age felt similar to me, which tends makes people think
-            you are male.
-          </p>
-          <p>
-            but... she was having fun being herself. being a legend of identity and of her skill in computer science.
-            winning the physics major. making cool shit at the hackathon, and probably in life. my perception of her was
-            the exact essence of who i myself wanted to be. i was jealous of her life.
-          </p>
-          <p>
-            i tried hard to avoid a breakdown. success. but i was feeling distant. the next hour or so was disorienting,
-            trying not to think about it too hard. i think there was one possibly interesting person we talked to. i
-            don't remember any of the other conversations. they were not important. but i couldn't think through them
-            regardless.
-          </p>
-          <p>
-            later, i decided to read some of her code. i either have a huge dislike towards the Rust programming
-            language and/or it was not high quality code. welp, so just is a person studying. my perception was just a
-            perception, inaccurate but impacting. i know i need to become myself, whoever that is. otherwise, i'm just
-            going to feel this shit at higher doses. i think about this every day, and the amount of time i feel being
-            consumed by these problems only grows.
-          </p>
-          <p>
-            getting through it all is a lonely feeling. not because no one is around, but because i am isolated
-            emotionally. i know other people hit these feelings, but we all are too afraid to speak up, and it's all
-            lonely.
-          </p>
-          <p>
-            waiting on a reply from someone from healthcare. it'll be slow, but it will be okay.

+<div class="for_everyone">
+  <p>today is my 21st birthday. april 30th, 2025.</p>
+  <p>it's been nearly six months starting hormones.</p>
+  <p>sometimes i feel great,</p>
+  <p>sometimes i get dysphoria.</p>
+  <p>with the walls around me gone</p>
+  <p>that shit hits way harder than it did before.</p>
+  <p>ugh..</p>
+  <p>i'm glad the pain i felt is now explained,</p>
+  <p>but now rendered in high definition.</p>
+  <p>the smallest strands of hair on my face and belly act</p>
+  <p>as sharpened nails to pierce my soul.</p>
+  <p/>
+  <p>it's all a pathway to better days; the sun had risen.</p>
+  <p>one little step at a time for both of us.</p>
+  <p>today i quit my job. free falling, it feels so weird.</p>
+  <p>like sky diving.</p>
+  <p>the only thing i feel is cold wind.</p>
+  <p>the only thing i see is everything,</p>
+  <p>and it's beautiful.</p>
+  <p>i have a month of falling before the parachute activates,</p>
+  <p>gonna spend as much time of it on art as i can.</p>
+  <p>that was, after all, my life plan:</p>
+  <p>i wanted to make art, all the time,</p>
+  <p>for everyone.</p>
+  <p/>
+  <p>then you see what happened</p>
+  <p>to the world and the internet.</p>
+  <p>i never really got to live through that golden age,</p>
+  <p>it probably sucked back then too.</p>
+  <p>but now the big sites definitely stopped being fun.</p>
+  <p>they slide their cold hands up my body</p>
+  <p>and feel me around. it's unwelcoming, and</p>
+  <p>inconsiderate to how sensitive my skin is.</p>
+  <p>i'm so fucking glad i broke up with YouTube</p>
+  <p>and their devilish friends.</p>
+  <p>my NAS is at 5 / 24 TB</p>
+  <p>and probably wont fill for the next decade.</p>
+  <p/>
+  <p>it took 2 months for me to notice my body changed.</p>
+  <p>that day was really nice, but it hurt a lot.</p>
+  <p>a sharp, satisfying pain in my chest gave me life.</p>
+  <p>learned new instincts for my arms</p>
+  <p>so they'd stop poking my new shape.</p>
+  <p>when i look at my face</p>
+  <p>it's like a different person.</p>
+  <p>she was the same as before, but completely new.</p>
+  <p>something changed</p>
+  <p>or i'm now used to seeing what makes me smile.</p>
+  <p>regardless, whatever i see in the mirror, i smile.</p>
+  <p>and, i don't hear that old name much anymore</p>
+  <p>aside from nightmares. and you'll never repeat it, ok?</p>
+  <p>okay.</p>
+  <p/>
+  <p>been playing 'new canaan' by 'bill wurtz' on loop</p>
+  <p>in the background.</p>
+  <p>it kinda just feels right.</p>
+  <p>especially when that verse near the end comes on.</p>
+  <p/>
+  <p>more people have been allowed to visit me.</p>
+  <p>my apartment used to be just for me,</p>
+  <p>but the more i felt like a person</p>
+  <p>the more i felt like having others over.</p>
+  <p>still have to decorate and clean it a little,</p>
+  <p>but it isn't a job to do alone.</p>
+  <p>we dragged a giant a rug across the city one day,</p>
+  <p>and it felt was like anything was possible.</p>
+  <p>sometimes i have ten people visit in a day,</p>
+  <p>or sometimes i focus my little eyes on just one.</p>
+  <p>i never really know what i want to do</p>
+  <p>until the time actually comes.</p>
+  <p/>
+  {/* FILIP */}
+  <p>i think about the times i was by the water with you.</p>
+  <p>the sun setting warmly, icy air fell on our shoulders.</p>
+  {/* NATALIE */}
+  <p>and how we walked up to the top of that hill,</p>
+  <p>you picked up and disposed a nail on the ground,</p>
+  <p>walking the city thru places i've never been.</p>
+  {/* BEN */}
+  <p>or hiking through the park talking about compilers,</p>
+  <p>tiring me out until i'd fall asleep in your arms.</p>
+  {/* ELENA */}
+  <p>and the way you held on to my hand as i woke up,</p>
+  <p>noticing how i was trying to hide nightmare's tears.</p>
+  <p/>
+  {/* HIGH SCHOOL */}
+  <p>i remember we were yelling lyrics loudly,</p>
+  <p>out of key yet cheered on because it was fun.</p>
+  {/* ADVAITH/NATALIE */}
+  <p>and when we all toured the big corporate office,</p>
+  {/* AYU/HARRIS */}
+  <p>then snuck in to some startup's office after hours;</p>
+  <p>i don't remember what movie we watched.</p>
+  {/* COLLEGE, DAY 1 IN EV's ROOM */}
+  <p>i remember laying on the bunk bed,</p>
+  <p>while the rest played a card game.</p>
+  {/* MEGHAN/MORE */}
+  <p>with us all laying on the rug, staring at the TV</p>
+  <p>as the ending twist to {/* SEVERANCE */ "that show"} was revealed.</p>
+  <p/>
+  <p>all the moments i cherish,</p>
+  <p>i love because it was always me.</p>
+  <p>i didn't have to pretend,</p>
+  <p>even if i didn't know who i was at the time.</p>
+  <p>you all were there. for me.</p>
+  <p/>
+  <p>i don't want to pretend any more</p>
+  <p>i want to be myself. for everyone.</p>
+  <p/>
+  <p>oh, the song ended. i thought it was on loop?</p>
+  <p>it's late... can hear the crickets...</p>
+  <p>and i can almost see the moon... mmmm...</p>
+  <p>...nah, too much light pollution.</p>
+  <p/>
+  <p>one day. one day.</p>
+  <p/>
+  <p class="normal">
+    before i go, i want to show the uncensored version of "journal about a
+    girl", because i can trust you at least. keep in mind, i think you're one of

+    <p>journal - 2024-09-14</p>
+    <p>
+      been at HackMIT today on behalf of the company. it's fun. me and zack were
+      running around looking for people that might be good hires. he had this
+      magic arbitrary criteria to tell "oh this person is probably cracked let's
+      talk to them" and we go to the first one. they were a nerd, perfect. they
+      seemed to be extremely talented with some extreme software projects.<br> okay..
+      oof... its still clouding my mind<br> i cant shake that feeling away
+    </p>
+    <p>hold on...</p>
+    <p>
+      at some point they open one of their profiles to navigate to some code,
+      and it displays for a couple of seconds: "pronouns: she/they". i don't
+      actually know anything about this person, but it was my perception that
+      she is trans. their appearance, physique, and age felt similar to me,
+      which tends makes people think you are male.
+    </p>
+    <p>
+      but... she was having fun being herself. being a legend of identity and of
+      her skill in computer science. winning the physics major. making cool shit
+      at the hackathon, and probably in life. my perception of her was the exact
+      essence of who i myself wanted to be. i was jealous of her life.
+    </p>
+    <p>
+      i tried hard to avoid a breakdown. success. but i was feeling distant. the
+      next hour or so was disorienting, trying not to think about it too hard. i
+      think there was one possibly interesting person we talked to. i don't
+      remember any of the other conversations. they were not important. but i
+      couldn't think through them regardless.
+    </p>
+    <p>
+      later, i decided to read some of her code. i either have a huge dislike
+      towards the Rust programming language and/or it was not high quality code.
+      welp, so just is a person studying. my perception was just a perception,
+      inaccurate but impacting. i know i need to become myself, whoever that is.
+      otherwise, i'm just going to feel this shit at higher doses. i think about
+      this every day, and the amount of time i feel being consumed by these
+      problems only grows.
+    </p>
+    <p>
+      getting through it all is a lonely feeling. not because no one is around,
+      but because i am isolated emotionally. i know other people hit these
+      feelings, but we all are too afraid to speak up, and it's all lonely.
+    </p>
+    <p>
+      waiting on a reply from someone from healthcare. it'll be slow, but it
+      will be okay.

+        warned.

+      <p>
+        all file dates are real. at least as real as i could figure out. when i
+        moved data across drives over my years, i accidentally had a few points
+        where i stamped over all the dates with the day that moved the files.
+        even fucked it up a final time in february 2025, while in the process of
+        unfucking things.
+      </p>
+      <p>
+        thankfully, my past self knew i'd want to assemble this kind of site,
+        and because of that they were crazy about storing the dates of things
+        inside of html, json/yaml files, and even in fucking databases. i'm glad
+        it was all stored though, but jeez what a nerd.
+      </p>
+      <p>
+        a few files were touched up for privacy, or otherwise re-encoded. some
+        of them i added extra metadata.
+      </p>
+      <p>
+        from the bottom of my heart: i hope you enjoy. it has been a nightmare
+        putting this all together. technically and emotionally speaking. i'm
+        glad we can put this all behind us, mark it as completed, and get
+        started with the good shit.
