There's a music hall in Waretown, NJ where I perform a lot. Senator Bill Bradley was in the audience one night. He's so tall that he had to sit in an aisle seat with his feet in the aisle. I almost stepped on his feet as I was leaving. A few years later, while I was directing traffic, I held things up so Bill could cross the street. I said "good evening", and he ignored me. I should have stepped on his feet when I had the chance. I've been told that Bill can be pretty rude.

Slightly ob/com behavior: if I brush up against something cold with one arm, I have to brush up against something cold with the other one, or I feel out of balance. Or I can rub the cold spot until it's warm, but I have to do one or the other.
