What annoys you?

Well, let's start:
It annoys me when you turn the volume up to the max, and the speakers start "hissing."
It annoys me when I try to explain something to stupid people, and they just can't seem to grasp it.
It annoys me when I encounter people with a messed-up sense of humor; I've seen enough of those in my life.
It frustrates me when I don't understand something and can't figure it out.
It annoys me when people like to show off, acting like they're the center of the universe, even though they're nothing special.
IT INFURIATES ME when I get kicked out of a game (or anywhere else) and get that "error report" that asks, "Send or not?"
It frustrates me when my computer is slow or glitches out.
It annoys me to hear domestic pop music in all its forms.
It annoys me when someone listens to that very pop music.
IT INFURIATES ME, you idiot!!!
It annoys me when there's no beer in the store.
It annoys me when someone goes to buy beer and brings back something completely different from what was needed!
It annoys me to watch soap operas about love (both domestic and foreign).
It infuriates me to watch "Dom 2." Of course, with Sobchak at the helm.
It annoys me when I'm busy with something, and someone interrupts me with trivial matters!
It annoys me when I can't find the "City Portal" spell in Heroes of Might and Magic 3.
It annoys me, and quite a lot, when something doesn't work out for me.
And after all of that, you remember that nerve cells don't regenerate, and that, by the way, is also annoying!
