Lately (and when I say "lately", I mean the past 4 years), I have had an extreme aversion to socialization of any kind. I'm not sure why... when I am around people I can handle socializing for maybe an hour, but after that, I'm ready to go back home and do my own thing.
or three years. I used to be fairly social and enjoyed conversations.
But now, it's all changed. Socialising for a couple of hours isn't too bad, but I get bored after a while and want to go home to my books and music.
I suppose getting older has contributed somewhat, as well...
