Anti-social academic

Here's a completely self-centered rant that I don't expect anyone to relate to, but hey, please indulge me. I F***ing hate professors that assign group projects. Give me any paper, any exam, etc., and I will work my ass off to do the best work that I can. But when I have to depend on two or three other people for a project - each of whom I assume to be a slacker somehow - then I get furious and stressed out. I suppose group $#!+ is part of life, and something I might have to deal with in any job someday. But I went back to school to avoid life, man. Dammit. This ruins my lunch.
