"I think being a woman is like being Irish." — Iris Murdoch

I was walking home, passing the Common, and this girl crossed the street to meet her friend.  They were both pretty clearly upset about something.  A guy in a van stopped and said, "Hey, you should cross in the crosswalk!  You're not supposed to cross in the middle of the block!"

The girl turned and looked him in the face and said, "You're not supposed to drink and drive, either."

He took off.  I though, Good catch!
