people who talk and touch you for no reason

not in a sexual way or anything, they're just annoying. Not even a "idk what personal space means" kind of thing, they just don't care. They think whatever they do is fine but I genuinely feel like crying when these people approach me, it feels like they cling on you like a parasite and won't leave u alone and every word that comes out of them spikes your blood pressure and makes u want to get hypnotic powers to make them leave and fall into a ditch. you won't even know them but they'll touch your hair and say smt like "your hair is all over your face, don't you comb it?" GTFO OF MY BUSINESS BITCH!!!!!! SHUT UP!!!!! they don't leave you alone even if you tell them politely, then they act like the victim when you do scream at them LIKE PISS OFF DUDE UGHHHH
