I'd say it's probably MOSTLY an IT thing to not want to talk much at non-social outings like this one. I agree with Bill. And I resent the comment that I am a douchebag because of it. It's not agoraphobia. It's I DON'T LIKE SMALL TALK WITH PEOPLE I DO NOT KNOW AND WILL PROBABLY NEVER KNOW. It's fine if you like it, but it's pretty intolerant if you can't respect that not everyone does (by the way this is directed at the person who said it was agorophobic and whom I CBF finding and quoting right now).
