• I fucking hate having sticky or greasy substances on my hands. If I am washing the dishes or cooking I might was my hands every time they get dirty just to get rid of the feel
• I can't watch something and eat at the same time
• It is very hard for me to focus on something if I am not in my room and/or there is someone next to me
• I speak loudly if I don't try to lower my voice consciously

I can't stand bright lights. the sun is fine, but in a building? forget about it.

Bananas. Uggghhh, that slimy texture. Texture is hugely important to me.

My food cannot touch on the plate. And I will eat my foods separately, too. All the veggies until they're gone, then all the meat and so on.

Shirts cannot touch too closely around my underarms and neck, so I'm sadly usually wearing shirts a size or two too big.

No tags, ever.

During cold weather, I wear sweatpants & shirts inside out because the way the seams feel next to my skin skeeves me out.

Socks make me feel claustrophobic.

I cannot sleep unless I'm naked.

Sometimes I have to pull my hair back in a very tight pony tail because it drives me crazy if it touches my face. At night, although I can't wear clothes, I must wear a little sleep cap to be extra sure my hair doesn't touch my face. (I often dream about shaving my head and feel the most exquisite relief. Then I wake up.)

I read 3 to 4 books at a time, switching out every couple of chapters. Don't know why, except that I love to read and there's so many books and so little time. I do finish them all, eventually!

There's more, but I'll spare y'all. I've been diagnosed with ADHD (it took years for my team of doctors to decide between mild autism and ADHD) and this thread is making me wonder if any of y'all divirge a bit from the norm also?

• I don't like warm, furry textures. This makes petting dogs, cats, and humans in fursuits a non-starter. Don't get me wrong, I love your cat and it is very cute, just not in my arms.

• I need to be very cold, preferably below 60°F.

• I don't like wearing clothes with text or any designs. It needs to be dark-colored and baggy.

• I generally don't like fresh fruits and vegetables. They have to be "in something". Texture issue.

• I am basically nocturnal. I just woke up.

• I prefer dark mode and night colors to the point that it is literally the first thing I check when I get a new piece of software, and there is a good chance that I will uninstall it if there's no dark mode.

• I don't like bright lights and colors in general.

• A necessary condition for me to remember something is that it makes sense to me at some level. I can't remember a list of random crap with no connection to anything else for more than a few minutes.

• I have a "depth-first" style of learning, which means that I gravitate towards learning topics as "deeply" as I can before moving onto the next topic. [1] But, this makes it very difficult to work with other students because they typically want to learn the bare minimum needed to pass the upcoming exam and nothing more. This is especially challenging as an engineering major with the breadth of topics I have to cover.

• I have a pathological need to justify my thoughts in detail, both to others and my future self. On the bright side, it makes my notes easy to read and my homework easy to grade.

[1] As an example of "depth-first learning", to learn probability theory, I learned measure theory first, even though it is typically taught "less rigorously" with its conclusions treated as unimportant details. Measure theory doesn't really have a practical use for engineers, because we typically work with the Dirac delta """function""" as if it is a legitimate point function instead of the Dirac delta measure or the distribution the measure induces, but for me it makes probability stuff easier to recall or derive when I forget.

So many, but here's a few:

-Can't stand the sun blasting at me, or bright lights. Darkness is good. -Have a long sleep ritual and special pillow (an old shapeless blop that I could not sleep without). I will organize my bed, bed linen, pillow and then ear plugs and a bluetooth face mask all of which has to be just right or I can't settle. Using separate bed linens is my best relationship advice because my partner is pure chaos and I am princess and the pea. -I eat things in particular ways, have always reorganized my burgers for example. -Loud sounds or off key music is painful. -Can't wear clothes that don't feel symmetric, like sock lenght or how tight shoelaces are. Can't handle clothes twisting or pulling anywhere, this is why I sleep nude no matter how cold it is. -Hair can't be touching face. -Hot weather and me don't mix at all. -My stuff always has a designated spot. If you move it, I will notice and move it back. No matter how small a thing it is. -Don't talk to me the first two hours after waking up. -Will infodump about anything, to anyone. -My hyperfocuses tend to land me in magazines or careers, I go all in on them. -Dark mode on everything. I game with screen filters on. -Need to feel clean, but skin can't feel dry. I swim in lotion. -Hair has to on the other hand feel and look superclean at all times. -I know most song lyrics by heart and have the most intense earworms with entire playlists of songs in them that can go on for weeks at a time. I have no control over this and any association can bring on songs like writing this is doing. -I think all the time. I analyze things all the time. There is never silence in my head. This is why I listen to stories for sleep or I would never sleep. My brain just keeps having interesting debates and ponderings about all the things. -I love nights. I never sleep nights if I don't have to, I thrive alone in the dark with my thoughts and always have. -I can't survive mornings, I burn out very fast if I have to work mornings for a long time even if I go to sleep early. -My sense of smell and taste are extremely good, can smell if someone is on their period for example. Strong flavours can be a problem. Things that others like, like saffron, taste metallic to me if used in the "normal" amounts. -I am an intense foodie and love perfecting flavour in foods. -Music makes me very emotional. The emotions are so intense I have had to back off from performing certain songs when I still sang because I can't keep it together at all. -Can't handle puke stuff at all, not even in tv or movies. It will make me sick instantly. -Can't play FPS games without getting intense motion sickness. Also can't watch videos while exercising at home without getting nauseous unless the camera is still and not in first person view.

Oh lol I could just keep on going, but maybe this is plenty. Anyone who reads all this is a champ.

I don't like the taste of bottled water, or the taste of water from a stainless steel bottle. Tap water in glass is the way to go

I have reusable plastic spoons (even though I know they're probably poisoning me with microplastics) because I can't stand the sound of scraping a bowl with a metal spoon

I pretty much wear exclusively cotton clothes because all the synthetics I've tried inevitably become scratchy. And then you have to deal with the weight of this shirt you once loved a lot becoming something that is too uncomfortable to wear. Cotton gets softer over time

My very-important socks strategy is 100% cotton, seamless, no elastic/very loose - inside hard bottomed slippers for walking around the house. This is the result of much research

It's really important to me that my living space is visually minimalistic (while still being cheerful) because I'm easily overstimulated that way. I don't much mind branded clothes, but I do dislike text on display in my home. I feel like it keeps my brain from resting

I can't use normal hair ties, they're always the wrong tension. I found adjustable ones instead

I basically can't do see soap suds or smell for doing dishes etc. It hard triggers every fiber of my being to be near it. So I can't wash dishes. Love to cook though.

I can’t start a sentence with the word ‘A.’

I need to shower every morning and after any activity where I sweat at all. And yes, I will shower as part of my morning routine even if I am waking up to go do a hike or something, and yes, I will shower after the hike as well. I will fixate on the feeling of dirt and grime on my skin if I don't.

I only wear "barefoot shoes" because normal shoes don't feel comfortable to me anymore and normal shoes make my back hurt. I am vegan because i am uncomfortable with the idea of eating once sentient things.

I share so many quirks with a lot of y'all. I like that it feels less like some thing my brain is making up and more like a reality we all live.

• I need to have my right ear covered when I sleep and the covers need to be snug over me or else I'm uncomfortable.
• (adding on) I do not like different food taste mixing. Food should either be sweet or savory but not both.

just some random stuff off the top of my head:

• I don't eat that black tip of a banana.
• I can't drink tap water.
• I don't like carbonated drinks and can't stand sparkling water.
• I can't wear certain type of rough synthetic fabric. For some reason it feels incredibly unpleasant to the touch. Don't know what it's called, but usually they make waterproof coats out of it.
• I wash my hands way too often.

pretty sure I have OCD so there are a billion tiny things I can list

I can't wear shoes without socks because I hate having sweaty feet but I am in a battle against time to get them off as soon as possible any time I get in the house.

I may just hate my current socks though.

i know i have more but i can only think of a few rn. i cannot eat cereal, and i can't drink any carbonated beverages. i can only rarely eat food that has touched each other and i just can't eat anything that has a certain strain of crunchy or leafy vegetables inside it (like, i need to request all lettuce, onions, etc are removed from every sandwich whenever i ever eat out)
