You forgot a category:

AS*H*&^E guy:
He is the guy that shows up at jet events and the local field with his jets and thinks he is above everyone else that doesn't fly a jet or his caliber of jets. He won't answer a question from someone interested in his jet(s) or someone interested in getting into the hobby. He is the guy that says, "If you have to ask how much, you can't afford it." He is also the guy who expects everyone at his local field to land for him when he fires up his jet because they should respect the price of what he has, although someone else has a 40% aerobatic plane worth just as much as his Jet. He is the one who crashes but it is ALWAYS equipment failure.
