pet peeves

Loud motor cycles, cap guns, angry music, damp towels, burnt espresso, half-done dishes.  That is a list of my wife’s pet peeves, that i can think of, off of the top of my head.
For me, topping the chart is:  Loud noises, after a long period of no noises.  Having my train of thought interrupted by anything.  SLOW COMPUTERS.  hardware issues.
Anyways, I think cap guns were invented solely to induce a pet-peeve rage.
