1. dogs barking in the middle of the night.-Shut up and go to sleep already!
2. someone jingling the change in their pockets absolutely drives me nuts
3. everyday my neighbor has the same van pull up in front of her house and he hits the horn about ten times in a row for her to come out on the porch. *beep, beep, beep* *beepbeepbeepbeep* Hello! I'm pretty sure she heard it the first time. I sure as hell did.
4. train whistles. I live next to a railroad track. usually they just blow the horn once and go right through town. but i swear between 3-5am they lay on that horn and blow it the whole way through town just to be a**holes.
