Today I'm wearing my Geek "mechanics" shirt, with the normal name patch over the left chest pocket reading "Geek." At work I've always gotten amused compliments, entirely from people who obviously know me and get it.
Today I'm at the gas station filling up, and the attendant says, "Why does your shirt say Geek on it like that?"
....how do you answer that, briefly?
I told him, "It's a computer thing." I don't expect he cared for a longer philosophical debate.
