I was going away for a few days and left my husband a list of chores. For fun, I put down as Item 5: Think about your wife a lot.
After I returned, my husband proudly reported that he had completed every job. When I saw the list, however, each item except No.5 had been crossed off. "What's this!" I exclaimed, "Didn't you think about me while I was gone?"
My chagrin vanished when he replied cheerfully, "I started to, but just never finished."
