I am very introverted, but you might be somewhat right about not actually disliking people, but more so the socialising with them. I don't even like to hang out with the closest people all the time, even though I like them.

There are very few people I let into my apartment, I hate having people over. Sometimes I hold afterparties and then it's somewhat alright to have people over, but I make sure to kick them out before the sunrise. Several people have tried to couch surf on my apartment and when I've said no, they try to plea that they don't have any other place, trying to get sympathy, but they underestimate how strict I am about letting people in. So they sleep outside or find another place, I don't care if it's -15 outside, it ain't my problem.
