There's a certain type of person I'm really shitty to and I feel horrible about it but I can't seem to help it when it's happening. If someone thinks theyre cultured cool and above anyone and theyre really not or its based on a naive perception I find myself being extremely rude. This has happened so many times and I always wonder what it is that causes me to be so mean to some people and so nice to everyone else, but I really loathe snobbishness of any sort and because of this I lash out. There's a fine line between being jokingly snobby and genuinely believing yr tastes are superior or youre better than someone for liking certain things. And the the thing is, when I'm around that type of person, I become that type of person? I begin acting like a snob to one-up their snobbery, my gut reaction is to let them know theyre not all that superior but by showing them how superior I am to them, even if I don't mean it (and im really really not), ugh. Then it becomes a sort of tug-o-war of tastes, until the problem, what annoyed me originally, just becomes greater and greater until we both spiral out of control. And it's so stupid of me, I should let them do whatever they want and live however they want, but theres something incredibly gross and annoying to me about that type of elitist attitude. I want to be nice to everyone and ignore those traits that bother me but I can't seem to help trying 2 "put them in their place". Probably because I've been there before and its nagl. It's immature and ugly and embarrassing. I need to just remove that toxicity from my life completely.
