I have been to parties, I have thrown some parties. Usually at some point I end up in the kitchen cleaning up. I'm not neat at all I can just relax better when I have something to do, and often someone else will come in and help me and we will talk. I have been to fancy dress up cocktail parties with wealthy and prominent people, they often find me amusing, I have had a few parties, some were so boring I wanted to leave, and one was so good people were calling friends, even though the beer was long gone. I don't know what makes a good party. I always have an exit strategy. I often find the few people I share interests with and monopolize them. (don't do this to the host) I do often leave without saying goodbye. It's rude, but I am never sure who to say goodbye to.
I have had fun at parties, and I have hated it and left, or wanted to leave. If I get ther eand it is loud and crowded I will start planning my escape. I don't drink or drug, so I am also at a disadvantage there. That used to help me fit in better, but I never could do it in moderation, and usually got stupid drunk.
