My husband grew increasingly displeased as our teenage daughter and her boyfriend studied in her room late one evening. Finally losing patience shortly after midnight, he knocked sharply on her door.  Her boyfriend immediately opened it and asked if something was wrong.  

"I have to ask you to move your car," my husband told him.  

"Oh, sure. Is it in someone's way?"  

"No," he replied, "it's parked at the wrong address."
