Mark Twain was an American writer. One
day, he went to Canada by train. He wanted to see his friends there. He was a
very busy man. He usually forgot something.
When he was on the train, the conductor
asked him for his ticket. Mark Twain looked for the ticket here and there, but
he couldn't find it. The conductor knew Mark Twain. She said, "Show me
your ticket on your way back. And if you can't find it, it doesn't
matter."
"Oh, but it does," said Mark
Twain. "I must find the ticket. If I can't find it, how can I know where I'm
going."
