In high school I was called tactless by one of my friends. I think that term fits pretty well.

On occasion I have been called a bitch. Killjoy was more common though. I'm just great at picking holes in every plan, it just annoys people because I'm none too good at thinking up new ones. The normal conversation is:

Me: (points out a load of things wrong)
Them: Fine! What's your plan!
Me: (shrugs shoulders) I don't know
Them: (Furious because I am telling them they're wrong but I can't do better)
