Zak's grandfather, Stan was very famous. Why? Because he had a very, very, very long white beard (胡子).
One day, Zak asked his grandfather, "When you sleep, do you put your beard over or under the quilt (被子)?" "I'm not sure. I never care about that," said his grandfather, "I'll look tonight."
Stan got into bed that night and pulled up the quilt. Then he remembered his grandson's question. Aha! His beard was under the quilt. But wait. Did that feel right?
He lift his beard from under the quilt and put it above it. This also didn't feel right. Si he put the beard under the quilt again. But he soon felt it would be better if it were out. The beard went in and out—first under the quilt, then over it, under, over, all night long.
Stan spent a sleepless night. In the morning, he was so tired and unhappy that he cut his long beard right off!
Stan's wife was so happy. She advised Stan to cut that beard off many times, but he never did it. Now a simple question made him do that.
