A lot of boys and girls in western countries are wearing the same kind of 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. When he was tired, he sat on a chair near the river. A child was standing on the other side of the river. “Oh!” The old man said to the person next to him on the chair, “Do you see that child with long hair? Is it a boy or a girl?”
“A girl,” said the person, “she is my daughter.”
“Oh, I am sorry. I didn’t know that you were her mother.”
“I am not her mother,” said the person, “I am her father.”
