My pet peeves are:
1. When someone puts in their photo, "Mary and I", please use "and I" correctly. It should be "Mary and me"... unless you are going to continue on with a sentence such as, "Mary and I were at Planet Hollywood."
2. Different color hangers.
3. Misspelled words and poor grammar.
4. Drivers that likes to weave in and out of lanes while in bumper to bumper traffic.
5. When my bf hits the snooze button over and over too! lol (totally agree with hviola)
