Now many boys wear the same(同样的)clothes as girls, and some of them have long hair. So sometimes it's difficult to tell whether(是否)they are boys or girls.

    One Sunday morning, I go for a walk with my grandfather in the park near my house. After a while, my grandfather is tired, so he sits down on a bench(长椅)near the pool.

    "Oh," my grandfather says to the person with long curly hair next to him on the bench. "Can you see the person with long hair on the other side of the pool? Is it a boy or a girl?"

    "Which one?" asks the person with long curly hair.

    "The one who is eating a hamburger near the pool," says my grandfather.

    "He's a boy," says the person, "he's my son, Li Yu."

    "Oh," my grandfather says, "I'm sorry. I don't know you are his mother. "

    "No, I'm not his mother. I'm his father. "
