Harry has always loved aeroplanes. When he was younger, he said, "I'm going to go into the Air Force," but his eyes were not very good, and he did not get in. Then he said, "I'm going to buy a small aeroplane, and I'm going to have flying lessons," but small aeroplanes and flying lessons are very expensive, and Harry did not have much money. But last year Harry found a new skydiver's club near his home. The lessons did not cost very much, and Harry began going to the club every Saturday and Sunday and having lessons. Now he is a good skydiver. Last week an old lady said to him, "You're a very brave young man. How do you jump out of an aeroplane like that?" "I'm not brave," Harry said and he smiled. "I'm in the aeroplane, and l say to myself. "It's going to crash in a few seconds!" Then i'm very afraid, and i jump out quickly."
