When George was thirty-five, he bought a small plane and learned to fly it. He soon became very good and made his plane do all kinds of tricks.
George had a friend. His name was Mark. One day George offered to take Mark up in his plane. Mark thought, "I've travelled in a big plane several times, but I've never been in a small one, so I'll go."
They went up, and George flew around for half an hour and did all kinds of tricks in the air.
When they came down again, Mark was very glad to be back safely, and he said to his friend in a shaking voice, "Well, George, thank you very much for those two trips in your plane."
Gerogy was very surprised and said, "Two trips?"
"Yes, my first and my last," answered Mark.
