At night I like to look around and feel the air on my skin. The air is still
|
||||||
|
but flowing because this place is well ventilated yet well heated and feels
|
||||||
|
nice, is a nice temperature. I like to look around at the walls and how they
|
||||||
|
blend into the ceiling, distinct only by texture and shade. There are no gaps
|
||||||
|
between them. Nor between the wall and the floor. The walls are clean here. So
|
||||||
|
is the floor. So is the ceiling. There are fire alarms and carbon monoxide
|
||||||
|
detectors and blinds on the windows and the air is nice but most importantly
|
||||||
|
the space is so big. A month ago I was waking up in a car, freezing. I was
|
||||||
|
freezing because the car had nearly no insulation and nearly no ventilation, so
|
||||||
|
my breath would condense onto any object that had some warmth to give it like
|
||||||
|
the windows or my blankets or sleeping bag. The condensation would cool me in
|
||||||
|
the night. I would wake up often in the very early morning hours shivering and
|
||||||
|
unable to get warm, kept awake by Kami insisting we not fall asleep or we could
|
||||||
|
die of hypothermia. I'd read Alias Grace or another book on my tablet, the
|
||||||
|
glass cold to the touch and foggy, wishing I was somewhere else, somewhere far
|
||||||
|
away where I couldn't touch the clean ceiling even if I stretched my arm out to
|
||||||
|
as far away as my fingertips could reach. Now I am here, the place of which I
|
||||||
|
dreamed. The walls are so far away and yet the air here, so much air, is so
|
||||||
|
warm. It's comfortable. I'm laying on a couch which is comfortable and using my
|
||||||
|
laptop comfortably and using wall electricity and laying in warmth and there's
|
||||||
|
a sink in this room or adjacent to get water on demand and there is fucking
|
||||||
|
laundry! I can do my fucking laundry! I can take a shower when I wish to! And
|
||||||
|
every night out of joy I cry myself to sleep. I sob like a little piss baby,
|
||||||
|
muffling my cries with my mouth or my will or when those fail the sleeping bag
|
||||||
|
in which I lay because I'm terrified that I will be back on the street again
|
||||||
|
and without the car and unable to get comfortable on hard surfaces anymore.
|
||||||
|
|
||||||
|
I met Toni in February, a 1999 green Subaru Forester or Forrester or something.
|
||||||
|
She was driven by my sidekick and in fine shape except for some difficulties
|
||||||
|
making it up hills. At the time my sidekick was considerably less so and I was
|
||||||
|
coming off some bad decisions with drugs and we were discussing some stuff and
|
||||||
|
I was in love with that car but never thought I would end up living in it. The
|
||||||
|
best weekend I'd ever lived.
|
||||||
|
|
||||||
|
I met Toni in a different light in September or so. I'd slept near a pile of
|
||||||
|
nearly unidentifiable corpses, the same hill about a hundred paces away, and
|
||||||
|
then went to work and pretended I hadn't. Then I scootered a ways down a hill
|
||||||
|
and up another to a different Burger King than the one at which I had worked
|
||||||
|
and crawled through the rear of the car, fringed with broken glass which did
|
||||||
|
cut me once or twice, and slept in the passenger seat in my sleeping bag. It
|
||||||
|
wasn't comfortable compared to where I am now but it was better than any of the
|
||||||
|
places I'd tried to sleep over that week and I got nine or so hours. I woke up
|
||||||
|
and went to work, the other Burger King, chipper. None of my coworkers knew I
|
||||||
|
was homeless but I didn't hide it. When I was homeless (technically I still am)
|
||||||
|
in Lewiston I wanted to actually let people know I was homeless because I
|
||||||
|
dispelled a lot of classic stereotypes about homeless people - I was educated,
|
||||||
|
sober, and employed. But rent money is not simply money but money in a bulk I
|
||||||
|
didn't have. The purpose of that job was to get the money to get where I am now
|
||||||
|
but I still can't believe I am actually here.
|
||||||
|
|
||||||
|
Sometimes when I close my eyes I see them, the corpses torn apart by something
|
||||||
|
of the forest, and I feel the exhaustion that rooted itself into my bones. And
|
||||||
|
I wake up and I'm hear under a clean ceiling and the walls are so far away. In
|
||||||
|
Toni I couldn't sit up without hitting my head, I had to duck or bend my back
|
||||||
|
somehow. I couldn't extend my legs. Here I can extend my legs however I want in
|
||||||
|
whatever direction I want. And pee as soon as I wake up.
|
||||||
|
|
||||||
|
I feel so fucked. My body is safe but my mind will not stop feeling like there
|
||||||
|
is something from which to run. I can't forget what I saw and what I felt and
|
||||||
|
who I was and what I did and being chased and losing trails and playing with
|
||||||
|
trails and tracers and the falling down hills and sirens and sillhouettes in
|
||||||
|
red and blue and making my way through dark alleys full of knives and shopping
|
||||||
|
knives and losing knives and cutting, others and myself, and biting belts as I
|
||||||
|
repaired my own mechanical faults and shocking myself until I forgot why and
|
||||||
|
waking up to screaming and waking up to screaming and waking up to screaming.
|
||||||
|
This is peace. What is peace?
|
||||||
|
|
||||||
|
Peace is the two library books I've read and returned since getting a library
|
||||||
|
card here. What If (2014) and What If 2 (2022). Neither really books I needed
|
||||||
|
to read or was recommended. Just books I wanted to enjoy. Peace is learning
|
||||||
|
Rust to contribute to friends' projects, using my laptop, drinking clean water
|
||||||
|
straight from the tap. Peace is riding in the car behind a few of the smartest
|
||||||
|
people I know who seem happy I'm here and safe, or at least that my body is
|
||||||
|
safe, but I don't tell them about the memories I can't get out of my head, just
|
||||||
|
the memories that haunt me but that are allowed to escape, to be forgotten
|
||||||
|
momentarily, that alone haunt my hosts. I still feel like I'm in the car
|
||||||
|
sometimes. I feel the old seat felt against the backs of my arms as I come to
|
||||||
|
from my sleeping bag. I see my breath fog in front of me. I don't but I do, I
|
||||||
|
see without seeing. Kami shakes me until I wake up. It's not safe. But it's
|
||||||
|
never safe, it's never safe because I'm still in the car and the lights are
|
||||||
|
pouring through the windows but it's the sun's light and it's through apartment
|
||||||
|
windows and it is safe here but it's not safe because the light is pouring
|
||||||
|
through the windows and I can be seen and someone is about to start yelling
|
||||||
|
that they will kill me because they don't see me as human and this was the only
|
||||||
|
secluded place I could find but it's not secluded because it's a floor behind a
|
||||||
|
locked door but it's not secluded so it's not safe and I'm taking up too much
|
||||||
|
space so my hosts are going to hate me but they tell me I can take up more
|
||||||
|
space certainly but I'm taking up too much space.
|
||||||
|
|
||||||
|
And I just want to go to sleep. I want peace. Peace was taken from me by those
|
||||||
|
who wage war on the proletariat. Whatever. I'm too tired. Could this even be
|
||||||
|
real? What happy existence? Am I really allowed to relax? Isn't it a trick?

Okay, so Rust is having issues with the lack of gcc here. It kinda sucks that
|
||||||
|
clap is using C stuff. I'm not sure if I should get this C stuff working first
|
||||||
|
or switch to a pure Rust argument parser.
|
||||||
|
|
||||||
|
Looking at this command line, it's LC_ALL=C PATH=[...] VSLANG=1033 cc [and then
|
||||||
|
a whole bunch of bogus] [cflags] -lgcc_s lc [and then more cflags]. What
|
||||||

|
||||||
|
|
||||||
|
At my most boring I have wished for a life worse than the one I have now. This
|
||||||
|
is the most enjoyable my life has ever been and yet it is unrelentingly
|
||||||
|
chaotic and I don't know how to get the pieces to fit. I feel irredeemable and
|
||||||
|
unable to relate to anyone or anything except perhaps a pebble being kicked
|
||||||
|
across the asphalt of the road or leaves falling off the trees, ripening,
|
||||||
|
wrinkling, from a soothing green to a reminder of the loss of youth.
|
||||||
|
|
||||||
|
One day I expected rain overnight so I slept in the passenger seat so I could
|
||||||
|
see the rain fall down the windshield. It was a view I had romanticized in my
|
||||||
|
head, one I wanted to pause and view for eternity. My sidekick did not. They
|
||||||
|
have places to go and things to do naturally so when it happened that we were
|
||||||
|
caught in rain and got to see rain fall over Toni we watched for a moment or
|
||||||
|
two and then drove onward toward the future, beckoning it without letting it
|
||||||
|
take its time. I was excited to be able to take this moment, though
|
||||||
|
unfortunately in solitude, at the pace by which I wanted to experience it. So I
|
||||||
|
fell asleep against the bitter cold of that parking lot and awoke to the pitter
|
||||||
|
patter of droplets against the glass before me and that was peaceful and I was
|
||||||
|
for a moment happy. But then I heard a colder, shriller tap from behind, and
|
||||||
|
turned around to find the cover for the rear window I'd fashioned out of
|
||||||
|
cardboard and plastic leaking by the seams, forming a puddle that would
|
||||||
|
inevitably fill with mildew and rot. I stared at this and realized my time in
|
||||||
|
Toni was limited. Toni would mildew, rot, and disintegrate, as had all my
|
||||||
|
relationships and all of my chances at housing.
|
||||||
|
|
||||||
|
After work I got back to the car and the puddle in the back was bad but in
|
||||||
|
getting into the car I had left my wet boots on the floor of the passenger seat
|
||||||
|
so the back was the only place in which I could sleep. My head curved away from
|
||||||
|
the active dripping I heard the clack clack behind me of rain making its way
|
||||||
|
through half a dozen layers of duct tape and mockig me before I sat up and just
|
||||||
|
fucking broke down. I couldn't stay in Toni but couldn't stay anywhere else and
|
||||||
|
I was out of options and just so fucking tired and cold and damp. There was no
|
||||||
|
one to comfort me and no solace to be had. My sidekick had left for another
|
||||||
|
style of adventure, everyone in my life had been either implicitly or
|
||||||
|
explicitly transphobic towards me, and I had inconsistent access to electricity
|
||||||
|
and clean water and hadn't showered in a week. It was the lowest point of my
|
||||||
|
life. To be wet and unable to be dry, to be cold and unable to be warm, to be
|
||||||
|
so tired and unable to sleep, to be so alone with nobody left. I sobbed like a
|
||||||
|
baby and didn't care who could hear me, the rain covered the sound and whomever
|
||||||
|
it revealed my cries could kill me for all I cared - I did genuinely want
|
||||||
|
someone to just open the car door and stab me, clutch me in a warm embrace and
|
||||||
|
spill my hot blood over me so I could just be warm for one fatal instant.
|
||||||
|
Nobody came. I fell asleep.
|
||||||
|
|
||||||
|
And from this dream I wake up to a ceiling so high and a floor so dry and air
|
||||||
|
unknowing of the sound of dripping agony but acclimated to my sobs which,
|
||||||
|
though muffled, do still call silently into the night after my hosts have
|
||||||
|
hopefully fallen asleep. And I don't know how to process being thrown from the
|
||||||
|
frigid shackles in which I'd been locked into the shocking freedom of domestic
|
||||||
|
cookie cutter monotony. I don't know how to fathom the stillness. I no longer
|
||||||
|
need to run but my muscles refuse to atrophy, instead slowly cycling in my
|
||||||
|
slumber lest I rise back to the street and to another abandoned car in another
|
||||||
|
parking lot. The gray pavement on which parking lots are drawn knows me better
|
||||||
|
than any four walls. Ceiling is not my usual blanket.
