Another thing I absolutely loathe is when I greet people, and they don't do as much as nod, just give me a funny look. Makes me feel like an idiot.
Also, people who brag about cheating others, and laugh about it.
And Princess made a good point- people who take credit for other folks' achievements and hard work. I've seen so much of this, it makes me sick.

People who don't respect night-time silence. I mean, for crying out loud, it's common knowledge that these buildings have sucky soundproofing- it's just malice or general 'fuckemall' attitudes with these people who go about playing loud music in the middle of the **** night, in the middle of the week and whatnot. I've had a lot of trouble with insomnia due to people like this, and there seems to be an ample surplus here. I've been popping sleeping pills on a nightly basis, and still I wake up to these dumbasses making a racket when everybody should be sleeping. Something horrid happens in my head every time I hear loud bass, especially at night time. Brings the worst out of me.
Even moreso if I lose my sleep over it. Even when a car drives past with a loud THUMP-THUMP-THUMP, I find my hand clenching into a fist.
I had to move several times because of folks like this. I'm regularly eating **** sleeping pills, and have made numerous (sometimes outright stupid) purchases to help me combat insomnia (earplugs, fancy sleep music). It's gone beyond the point of being a bad joke. My brother must think I'm crazy for always having 'noisy neighbours', because 'nobody has that sort of luck three times in a row'. And insomnia brought it's buddies into town, and they're having a blast in my body. *Sigh*

Haven't had a lot of problems with salesmen- generally when they call me, I simply say 'What are you selling?' shortly followed by 'I only make purchases out of my own initiative, sorry'. And my door's buzzer is out of order, so I don't usually have to deal with messengers of God or vacuum salesmen.
