Honestly, depending on the party I just don't even go. The loud drunk type of parties that a lot of people are talking about here are absolute misery for me. I just wind up standing off to the side, too shy to strike up a conversation with any of the various strangers around, and eventually just leave. Eventually I stopped going to such parties because I just wind up feeling awful about myself afterwards. On the other hand, I love having dinner parties with friends or family, because then I actually can talk to people and have a nice time. Both of those things are parties, but they are both very different experiences for me.
