My spendthrift wife, who has a terrible habit of squandering money, was dipping into our savings without my permission. I finally snapped and scolded her, but she got mad and stormed out of the house... Left alone to deal with the chores, I was at my wit's end when her mother rushed over, apologizing profusely and saying, "My daughter is so sorry... I'll take care of everything around here until she gets back..." So, I figured, why not? I ended up getting her to do all sorts of things in my wife's place...
