We have a stringent rule against chewing gum in our house, which led
to the following amusing episode:

My wife and I were discussing with our children a recent accident where a
man died trying to save his wife. My wife said that she would rather I
stay alive to take care of the kids. I said to the kids Wouldnt it be
terrible if Mommy and Daddy both died in an accident? The seven year old
solemnly agreed that it would be terrible. The five year old thought for
a few seconds, then brightened and said, At least we could have gum!
