A couple was selling their house. The mother stressed emphatically that her sons must make their beds each morning. She left for work before they left for school, and she wanted to be sure that the house looked presentable when the agent showed it to prospective buyers. The mother was surprised and impressed that her 15-year-old son's bed was perfectly made each day. One night when she went into his room, she discovered his secret. He was fast asleep on the floor in his sleeping bag.
