Perfectly Made Bed

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.
