I have a slight case of OCD, so I get upset when somebody turns up the volume on the TV and it lands on an odd number. Everything has to be even numbers with me or I go crazy.
I also get upset when people who mean well make hurtful comments about my pregnancy, like "Wow, you look like you're about to pop" or "Are you sure it's not twins?" As if I didn't already feel like a whale.
With certain people, just the sound of their voice annoys me, and I have to leave the room. Some people just don't have very nice voices. My own voice bugs me sometimes.
