The kids started asking me riddles that they had learned in a joke book. It was clear that I was in a different state of mind than the kids…
Child: Daddy, what can you eat, but not for dinner?
Dad: Your words.
Child: Um, no. The answer is ‘lunch.’
Child: What can be served, but not eaten?
Child: <pause for reflection> No. The answer is ‘a tennis ball.’
Child: What city has no people in it?
Child: <sigh> Electricity!
