honestly i do quite enjoy them, in the right circumstances. i do not like going with people i'm not close with. last time i did that (new year's, year before this one) was a nightmare. went with a cousin i hadn't seen in years and all his friends and didn't know anybody, it was awkward and awful.
but going with someone i'm close with, as long as there's at least one person for me to chat with while i'm drunk/high, i can feel great. i definitely enjoy the feeling of being around people, and being under the influence of something helps with my social anxiety a lot. (why i have to deliberately make sure not to do it too often, because i know i could get addicted)
i've been called an ambivert, not entirely sure what i'd consider myself. it's not like i get invited to a lot of parties anymore. oh, i do hate those super stuffy "parties" my mormon relatives throw. cannot stand holiday get-togethers either, other than halloween (but that's much different than christmas/thanksgiving gatherings, which i abhor.)
anyway, nuance, i do think i can be fun if the circumstances are right and i feel safe/comfortable enough to be myself and relax!
