What are the small things that irritate you?

For me, the following things drive me bonkers!
1) Hearing people chew, slurp, crunch, smack, lick. Mouth sounds in general.
2) The Dominos pizza app says my pizza is ready, but when I arrive my pizza is in fact NOT done and still in the oven.
3) My boyfriend shakes his leg when he's bored, and if it touches my body or moves the furniture I am sitting on I can't handle it.
What weird small things can you not handle?
