I tend to be polite to people I don't know, and totally honest with people I do know. I try to think about other's feelings. I don't like gossip (It's usually very boring). I make jokes, favoring absurd-ist humor and bad puns. I don't talk while watching movies/TV (at least not during good TV). I get along with most people, but actually like very few people. I'm very patient, except towards willful ignorance and incompetence (as in: you've refused to learn after being told several times). I don't take most small problems, insults or inconveniences personally, and generally pity those who do. I like to solve problems and puzzles. I'm usually very kind.
I prefer the indoors, and dislike crowds and concerts. I don't follow sports.
I looking to date girls who are single and looking for a relationship. I'm not interested in F***buddies, flings or one night stands. I'm especially not interested in open or poly relationships (those are for people who are lazy and/or self-centered and/or natural cheaters).
Games are important to me. Video games, board games, RPGs. if it's got rules to learn and exploit, I'm in. Though I don't really care for most FPSs, and fail to see the point of playing a Sports video game. I've played mostly Console and portable games, and only gotten into tabletop RPGs more recently (last 2 years). Games have been with me since I was very small. My grandfather gave me a Gameboy when I was 5, and I'm quite attached to them. It's not something I'm ever going to "grow out of". The way people get "wrapped up in a movie", "settle in with a good book", "get lost in the music at a club or concert", those are feelings I achieve through games. If you're not a fan, at least respect it as a worthwhile pastime.
Science is the only way we can actually know anything. Rational thought is what separates us from the beasts and the humans who have difficulty understanding why we need pants. If you have a religious preference and don't mind a dirty heathen that's fine. I try to be a good person because it helps others, not because of divine judgement.
I like sci-fi and fantasy. I like reading manga more than watching anime, because of the pacing. (though both are usually better than western comics and super heroes) I like Doctor Who, Fringe, Lost and any other show that can mix sci-fi/fantasy with good writing and characters.
I'm socially liberal and fiscally moderate. I like to talk about politics, but don't have to. That said, I really can't get along with socially conservative people. Fiscal conservatism is a policy that can be defended, and we could actually talk about it, but I can't get along with people who are scared of gay people getting married. Someone as funny as David Sedaris should be able to marry anybody he damn well pleases.
Most of the questions asked on this site could have a number of caveats or exceptions. This is also true of most situations in Life. I try to base my decisions on as much information as possible, and avoid sweeping declarations. This may in fact be the most important part of my character. Reasonability, and flexibility in opinion and viewpoint. I abhor stubbornness, and people who refuse to let their minds be changed. Which, ironically, is an opinion that I will never change.
