It seems to piss other people off that I know a lot of stuff.
I fully admit that most of it is useless trivia, or represents a surface understanding of a much deeper topic, but the impression that I seem to give is that I'm a know-it-all.
But I can back it up.
I do have a tendency to be condescending toward people. The reason for this varies from person to person, but the most typical would be "individual x is as dumb as a post."
