1. Bad hair days. Really, it drives me crazy when my hair doesn't cooperate with me. Which happens more than I want it to...
2. Rudeness. Which can come in many forms and they all annoy me.
3. The sound of an alarm clock in the morning.
4. Over-thinking of situations. I do this too much and that's probably why it bothers me so much.
5. When people make fun of Hufflepuffs.
