Our stomach naturally produces hydrochloric acid. It's corrosive and can burn through your skin and tissues. Bbuuuuutttr our stomach lining is covered in mucus to prevent us from eating inside out.

Have you seen hydrochloric in a science experiment? That chemical reaction is insane! Makes sense as we eat meat, bones, and cartilage sometimes. If not our poop is gonna be bony...

The fact that all those other people you see out in public all have their own lives that they go home to completely separate from yours.

Languages, or just talking in general. The fact that we’ve given meaning to a bunch of random sounds made by our vocal cords is bizarre when you think about it. Like, how did this even start? How were we able to decide what should be called what? For example, how did we decide that rock is called rock or that the sky is called the sky?

Paparazzi: they do everything just like a stalker, yet they’re not incarcerated for it and paid to do the things they do.

The fact that a majority of people think in images. Like, think of an apple and see, in the mind, a picture of an apple. So weird to me, I’ve never “seen” anything up there.

Clapping, animals must think we're mental. Apart from seals, seals know

The internet. How it works, and also just the whole concept of it. Complete strangers on literally the other side of the planet can interact with me almost instantaneously.

As someone from an Asian cultural background, how American kids can get financially cut off from their families at 18. Like, they’re still a family and on good terms, but my friends have said stuff like “my mom owes me 300$”, or that they’re taking out student loans though their parents are financially able to support them through college.

But, their parent’s money isn’t their money anymore so they have to take on debt. It’s so strange to me, as the expectation in (most) Asian households are that parents support you financially when you’re young and then you support them financially when they’re old, and there’s no clear demarcation of my money your money.

Reading. Like, there are these random squiggles and we can instantly interpret them into complex thoughts, concepts, feelings, emotions - from people we’ve never met or sometimes even heard of before. It’s weird.

The concept of laughter. Why does our face contort and our diaphragm spasm when certain things happen? and how do our brains decide what things are funny and what things aren’t?

Dreaming. Whole worlds, people following some kinda plot. Coming to the same places in different dreams, sometimes years away. Then we wake up and puff! Off it goes

As a Deaf guy, looking at people kissing musical instruments is quite bizarre

Having pets. I have two dogs that I love to death but when I really think about it, I realize they’re just two random animals that I saw one day and said “yeah I like that one” and put them in my home against their will and I give them food regularly and smother them with more affection than I give to other people. And those two random animals seem to think that’s totally dope and show signs of liking me back.

Crying, why does my body create liquid from my eyes if something is sad

Birds having a built in GPS system. They can fly south for the winter, then fly back to the exact same tree up north.

Teeth. I don't know why. Your teeth are the only part of your skeleton that you can see. You bleach 'em, you lose em, you put metal racks on them so you remold your bones to the shape that society finds visually appealing. There's a fictional woman that breaks into your house to pay you for these bones. It sounds like a straight up sociopath. We get film on them that calcifies & solidifies & makes other bone-like material. Like teeth are weird, dude.

Balloons. Like here, have a sack of air.

Getting a sense of deja vu. I know many people experience it but mine is so vivid sometiemes i know what the next thing that is going to happen or the next thing someone is going to say. it doesn’t happen often, and it’s always the most insignificant moment (never a life changing or major event by any means).it’s a completely understood emotion/feeling than many people feel and understand it as “simple case of deja vu” but they treat it so minor. it’s weird and no one acknowledges how weird it is

As a dog owner and cat owner I sometimes look at them and think, "there is literally an animal living in my house whose ancestors ran free and hunted other animals and it is just laying upside down all cute on its bed beside me and also can't eat unless I give it food". So I guess that.

Following celebrities blindly and caring about their opinions

Allergies. Like how the f**k does your body become deathly allergic to something that isn't capable of killing another person. Please someone explain that s**t.

Dancing. Like people flail around in weird and awkward ways to sounds.

Having kids. You're just gonna make a person? You're just gonna snatch an innocent soul out of the void and force sentience upon it? What the hell.

As a left hander, watching right handers write. Yeah, I get it. I am the odd one out. But still.... Come on, fellow left handers, back me up on this.

There’s a limitless, boundless void not that far above our heads we have no control or understanding of, and people don’t seem that concerned about it…Ppl will be like see that star? It’s hundreds of millions of light years away. Maybe it’s already dead. Cool, huh? And then they just go on about their day.I think the Romans and Mayans had it right. Gotta be more careful around the stars, you never know what could happen.

You can be overwhelmed or underwhelmed....but never just whelmed

Earrings. Drilling holes in your body to hang decorations from.

My tongue is a meat tentacle

The fact that almost everybody finds somebody's butt attractive.

Being alive, in this world…

Some mold is edible. No matter how stinky it is.

I can't imagine ever taking a group shower in a locker room setting.

Gravity

Using sharp metal to scrape hair off of my face.

Cheering in a crowd. I just can't bring myself to woooooooo!

Keeping fish as pets. With other pets you can cuddle, pet, and play with them, but fish just sit there in their tanks and some people use them more as like a living decoration.

Scrolling. Like wtf you just rubbing the phone screen.

Swinging our arms while walking
