My main pet peeve only concerns me- I don't like hair on myself. If it was socially acceptable I would get all my hair permanently removed (yes even my head and eyebrows). I especially hate the feeling of my wet (head) hair on my skin in the shower, to the point where when I wash it I tilt my head away from my body so it doesn't touch me, and when I am done I tie it up in a bun for the rest of my shower. BUT this only applies to me. I don't mind hair on other people, in fact I love doing my friends' hair (braids, ponytails, brushing, cutting, etc). For some reason I just don't like the feeling of hair on myself. Idk why....
Another pet peeve I have concerning other people is- when strangers don't get my cues that I'm not interested in making conversation/small talk. I like doing my own thing sometimes and I'm not one to talk to the average stranger, so when someone sits next to me on a plane and starts talking to me for example, I usually try to politely let them know I don't want to talk by using social cues. I know there are those that have a hard time understanding social cues, but I actually don't mind talking with those types of people, and my pet peeve is centered around the average "small talk" neurotypical people like to make. To me small talk with random strangers is not fun, and can even be stressful, so I really don't like it when people continue talking to me when I try to politely tell them to stop (but I'm not bold enough to just say "please stop talking to me" so maybe thats on me lol).
