1) Slow drivers. You know the guy in front of you doing 15 in a 45.
2) People who talk down to me, as though I am unable to understand simple concepts, like nuclear fusion or how a carberuator works, because of my appearance.

Being harrassed by Christians because I am wearing black and therefore must worship satan, even though I am wearing 6 crosses (i really like crosses, okay?) and no upsidedown pentagram.
4) People who think Marilyn Manson is so goth and the greatest thing since sliced bread.
5) People who think sliced bread is so great. How freaking hard is it to cut a slice of bread?!?
6) Automated phone systems. I'd just once like to talk to a human being.
7) Floruscent lighting. Hurts my eyes and gives me a headache.
8) China (the country)
and finally,
9) People who know shit about cars. I work in an auto parts store and you can't imagine how many times I've had the following exchange.
Customer: The mechanic said I need a (insert name of automotive part here) for my car.
Me: All right, what kind of car are we working on?
Customer: It's blue.
Me: (starting to get irritated) What year is it?
Customer: I think it's a 1990, or maybe a 1993...
Me: (becoming quite irritated) Ooookkaaayyy... (deep calming breath) What kind of car is it? (speaking slowly and enunciating carefully as though talking to a three year old)
Customer: I told you, it's a blue one.
Me: (now about ready to leap over the counter and strangle the ignorant bastard to death) Sir, why don't you go back to your mechanic and have him call me.
Customer: But don't you have the part?
Me: (attempting to keep my blood pressure below 500psi) Sir, we have a lot of parts, but until you can tell me the make, model and year of your car, I don't know which one to give you.
Customer: But I told you I just need a (insert name of automotive part here again).
Me: (fakes a seziure to get out of talking to this ignoramous)
That's not even close to all of them, but I won't put them all down here. Please, for the love of god, everyone who reads this, know what kind of car you have.
One more thing, this damned message board telling me that I'm not logged in if I spend more than 2 minutes typing a reply to a post up. GRRRRRR!!!!!!!!!!!
