Bob and his wife lived in a peaceful town happily. They usually went to the same barber shop to get their hair cut. The barber was a humorous man and liked to tell jokes. And he liked to ask others to guess his riddles. Many of his customers loved him and his riddles. But he had never asked Bob before.

One day, when Bob was in the barber shop, the barber decided to ask him to guess a riddle,“This is a person who is my parents’ child. But this person is not my brother , and is not my sister, either. Who is this person?” Bob thought for a long time and finally gave up. The barber laughed and said, “This is me!”

Bob liked this riddle very much. When he returned home, he asked his wife to guess the same riddle, “This is a person who is my parents’ child. But this person is not my brother, and is not my sister, either. Who is this person?” His wife could not guess it. Bob laughed and was almost out of breath. He said, “Don’t you know him? This is the barber from our barber shop!”

His wife’s face turned red and she was very angry. Then she said, “How stupid you are! It’s actually you.”
