There are really only two things that will make me shit-throwing screaming punching angry, and that's someone saying something under their breath to me or slamming their door.
As a result, I never say something under my breath. If I want them to hear it, I say it, and if I don't want them to hear it, I think it. I've been around way too many people who would close a conversation with a passive-aggressive something-or-other under their breath as a way to "get the last word in" and I just can't seem to handle it anymore. Now I'll just walk right up to them and say "WHAT!?" ... think Samuel L Jackson..
Another vote for the up one aisle, down the next and staying waaay behind the girlfriend when we shop.
