Funny Story!

Mr Walker had one son. His name was Harry, and he was twelve years old. Mr Walker went to work by a car every day, and he took Harry with him to his school. Harry wanted a bicycle very much. 'A lot of my friends ride to school on their bicycles, 'he said to his father. A few days ago, Mr. Walker stopped his car at a red light, and then he said to Harry, 'I'm going to give you a bicycle next month, Harry. But first I'm going to ask you some quesstion. Now, do you know the meaning of these traffic lights?' 'Yes, I do,' Harry asnwered quickly, "Red is "Stop", green is "Go", and yellow is "Go very fast"!'
