     One day, Tomas Jefferson, the president of the USA, was crossing a river with a group of travelers.

The river was overflowing its banks. So it was very dangerous to cross it on a horse. Each man was

fighting for his life! Then another traveler came and he wanted to cross it, too. But he didn't have a horse.

He watched the group and then asked Jefferson to take him. Jefferson agreed immediately. The man climbed

on. After they were both safe to the other side of the river, someone asked the man,"Why did you ask

present for help? Did you know him?" The man was shocked because he didn't know Jefferson was the

president. "All I know," he said, "on some of your faces were written the answer NO, but there was the

answer YES on his face."
