When I was a boy, I didn’t have any hair on my head. So I was very shy. I liked to watch my friends play in the park. Sometimes I would join them, but most of the time I just watched them play.

Every day, we would see an old man walking in the park. He had big ears and no hair. We thought he was dumb (哑的). Every time when my friends saw him, they would say loudly, "Hey, Mr. Dumb, what’s the time?” But they got no answer.

One early evening, I was standing outside my house, and I saw the old man coming. I was not with any of my friends and there were no other kids around to say the usual words of "greeting( 问候)”.

But how could I let the old man walk by without saying anything? So for the first time, I asked, “Hey, Mr. Dumb, what’s the time?"

The old man looked at me. Then he looked at his watch and answered, "It’s six thirty. " I ran into my house and never said that "greeting" to the old man after that day.

小题1:The boy often played with his friends together.

小题2:The boy’s friends were very polite to the old man.

小题3:Neither the boy nor the old man had any hair on the head.

小题4:Actually, the old man could hear and speak.
