When I called my parents to wish them a happy New Year, my dad answered the phone. “Well, Dad, what’s your New Year’s resolution?” I asked him.
“To make your mother as happy as I can all year,” he answered proudly.
Then mom got on, and I said, “What’s your resolution, Mom?” “To see that your dad keeps his New Year’s resolution.”
