I usually let cars out - my good deed for the day done!

In supermarkets... depends on DS. If he's in an OK mood then someone can cut in front. If he's getting itchy to get out, then sorry mate, I was here first and have a cranky son.

I hold open doors, say "thank you", give old ladies lifts home, share my son with the neighbourhood old ladies, stop children running away from their mothers (WISH someone would return this favour!) and am generally community-minded. Getting rarer where I live, but not dead completely!
