Videos

I'm not sure quite how watching videos at parties started to bother me; I know it's much more fun to laugh at stuff with other people than by yourself, so watching funny stuff has its advantages as a social activity. But when someone starts playing videos, I usually have fun, but it doesn't seem quite "social" enough to me. I prefer playing games (though I know people who don't find games "social" enough for their tastes); probably I find it important that you're still interacting meaningfully with your companions in a game.

Videos at parties bother me less if I'm expecting it (e.g. going to someone's house specifically to watch a movie); I guess I get a little disappointed when I expect to hang out and chat, but end up spending most of the time staring at a screen.
