Here's a bumper sticker I'd like to see: “We are the proud parents of a child who's self-esteem is sufficient that he doesn't need us promoting his minor scholastic achievements on the back of our car.”
People piss me off like the ones who point at their wrist while asking for the time. I know where my watch is buddy, where the hell is yours? Do I point at my crotch when I ask where the bathroom is?
