Why don't I make a list? I mean, god forbid I lose track! And I'm in such a cynically sarcastic mood right now, too!
If I've missed anything, don't be shy about letting me know.
I really don't think I'm gonna come close to covering it. Forget the tip of the iceberg - I'll be too far away to even see the tip of the iceberg. I'll just stop when I get tired of it or something - to be continued later, perhaps.

People who are basically the whole reason you have a middle finger.

Being caught in a ridiculously long conversation on a completely retarded/unimportant/trivial subject, with no end in sight.

Overwhelming suck-ups and annoyingly ignorant sycophants.

Sheltered people who live in a fairy land we call "blissful ignorance".

Being stuck in traffic with people who can't lay off their horns and chill out, not for a second. (I swear, you can actually learn new curse words here)

The person who wastes the time to sit there watching you fix something or whatever, solely for the purpose of pointlessly screwing it up as soon as you're done.

The person who compulsively goes on about trivial things like it's life-and-death, being a dead horse 'til it looks like freakin' hamburger meat.

When someone kicks the person who knows what they're doing out of their way, and tries to take their place with the only result being that they'd wasted your time and made a complete idiot out of themselves.

When the person making you do all their work excuses it by saying that you need to be less "selfish".

People who are blindly self-righteous and always see others as being wrong.

Cell phones. Because people who are standing less than five feet from each other will be texting one another. Because people keep talking on them, while they're driving, and end up wrecking. Because it's freakin' annoying when someone's ringtone goes off in the middle of a movie theater at the best part of the movie!

People who aren't cool, but try to hard to be that they just embarrass themselves beyond any redemption.

Feeling crappy and unmotivated, in the general sense, as if you've no purpose in life at all.

Whiny brats who complain about every little, tiny problem like the freakin' skies falling.

When you say "hello" and get "Whaddya want?!" I mean, sometimes the person's just having a bad day - other times, though, it's the kinda person who always says that like they're permanently got somethin' stuck up their hind parts.

Having to repeat myself, when people don't care enough to listen in the first place or don't care at all.

Narrow-minded people who can't imagine a world with options.

People who disagree with another's hobbies, and insult something a person may have really cared about because they think it's a "waste of time" or whatever.

Decent people gettin' crap you know they don't deserve.

Being unable to help a friend.

When something's all organized and uniform, then suddenly there's that one thing that's out of place and you can't stop staring at it. (yes, a little mild OCD perhaps)

People pushing their responsibilities on you, either with a lame excuse or no excuse at all.

Not being left alone, and with no time to simply relax and unwind on your own.

Whores who end up with no self-worth other than what someone'll pay for 'em.

Adults with the mentality of a freakin' toddler.

The person who gives you a job, sits there doing nothing, then keeps complaining 'cause they don't like how you're doing your job.
