I prefer small gatherings to large, and most enjoy having friends over, cooking, and then playing games, watching DVDs or just chatting, listening to music and drinking.
I'm a geek and a gamer, but I'm very active when I find something I enjoy. In Oslo it was cross country skiing and ice skating, in Canberra it was cycling - this place is great for cyclists - got to find something for San Francisco - update: it's rockclimbing!
While I make games for a living, many of my friends are non-gamers and that's fine. All of them at least respect my passion for games though.
I speak Chinese, but love Europe and would love to learn French, German or Italian. I never did get a good handle on Norwegian.
