My husband, Michael, and I were at a restaurant with his boss, a rather stern older man. When Michael began a tale, which I was sure he had told before, I gave him a kick under the table. There was no response, so I gave him another poke. Still the story went on. Suddenly he stopped, grinned and said, "Oh, but I've told you this one before, haven't I?"
We all chuckled and changed the subject. Later, on the dance floor, I asked my husband why it had taken him so long to get my message.
