I'm a pretty big loner. I've had a lot of friendships end because of it, the other person is an extreme extrovert and takes it personal.
I never make plans with people because in my head it sounds good, but then when the time comes I'd just rather hang out by myself listening to music, reading things I find interesting etc etc
social interaction drains me. "people empty me, i have to get away to refill" is the best quote to describe it.
it also pretty much fukks up any sort of relationship I could have because seeing a person I like once, maybe twice a week is enough for me. and people can't handle that. they need more out of me, and i can't give that to them.
