My wife had saved a slice of expensive cake in the refrigerator and specifically told me not to touch it. At midnight I ate it. The next day she asked what happened, and before I could stop myself, I said our teenage daughter had probably taken it.
My daughter looked at me, understood immediately, and said, "Yeah, sorry." Later she demanded payment for her silence. For the next month, I had to drive her everywhere without complaining. I deserved every minute of it.
