Not guilty (touch wood). Ever have someone do something to you (hit you with the shopping cart, step on you, or hurt your feelings type things) and you SAY 'oh that's ok", but what you really want to do is smack them up alongside their head?
Guilty, several times over; as well as on TV (the news) and interviewed on radio. But that was eons ago. Ever say Hi to someone and then realize they aren't who you thought they were?
