A boy who was cleaning the shoes in the street said to a young man passed by, "Let me clean
your boots. It just spends you only a penny." But the man refused. Then the boy told him that he
will clean his boots for nothing. The man agreed, and soon one of the boot shone brightly. Then
he put the other boot on the box, and the boy refused to clean it if he was paid two pence for his
work. The young man refused pay something and went away. But the well-cleaning boot made
the dirty one so badly that he could not walk on. He turned back and gave the boy two pence.
