A lot of boys and girls in America are wearing the same clothes and many of them have long hair. So it is often difficult to tell whether they are boys or girls.

One day an old man went for a walk in a park in Washington, and he was tired, he sat down on a bench(长凳). A young person was standing on the other side of the pond(水池). "Excuse me," the old man said to the person next to him on the bench, "Do you see the person with the red trousers and long hair? Is it a boy or a girl?"

"A girl," said his neighbor, "She is my daughter."

"Oh," the old said quickly, "I am sorry, but I didn't know that you were her mother."

"I'm not," said the other person. "I'm her father."
