I hate when you’re in a conversation with somebody and you are telling them something and the person you’re speaking to says “Ok” after each pause. I’d much prefer an ‘Uh-huh” than an “ok.”

I also hate it when you’re talking to somebody and they get a kleenex or a handkerchief and just start going to town in their nose, as if you weren’t there. Can you possibly wait a minute to pick your nose? Must you do it in front of me?
