I just had to share a cute story. I had picked up my boys from school and we were meeting a school mate for a play date at a local park. There was lots of traffic, and we found ourselves sitting through a lot of lights, which rarely happens where we live. So David, my 5 year old said: "Why are there so many cars?" To which my son Thomas (8 years old) replied: "It's rush hour." So David in his most serious voice said, "If it's rush hour, why isn't anyone rushing." I couldn't have said it better my self.
