Sorry about What?

An idea just came to me for a good slogan for a t-shirt. It would have, "Sorry about What?" boldly blazoned on the front. It would catch the eye of all those people who keep saying, "I'm sorry" to me whenever I cross their path in a Walmart or a grocery store. Maybe I'd irk them before they even get a chance to irk me by saying they're sorry we just crossed paths or they're sorry I just came too close to them.

There's already far too much sorrow in the world. Why cheapen the word by using it every chance you get!
