Once upon a time, there was a little boy named Tim. Tim was very tired. He had a letter in his hand. He wanted to pay for a toy.
Tim walked to the toy store with the letter. He saw a big, red ball. He wanted the ball so much. Tim gave the letter to the man in the store. The man looked at the letter and smiled.
The man said, "This is not money, but it is a special letter." The man gave Tim the big, red ball for free! Tim was so happy. He went home and played with his new ball all day long.
