-When men who are over 40 years old whistle. I'm not sure why it's only men over 40 that bother me when they do this (a 45 or 50 year old guy did it today at the store in my line and I wanted to strangle him) but I was fine when my 16-year-old coworker did it later on. If a woman whistles it doesn't bother me either.

-When people get drunk.

Those are the only ones I can think of right now actually. I have a pretty big list of them but cba to type them all out right now.
