When a boy was taking his father's dinner to the factory, he stopped for a minute to watch a workman cleaning a sewer.
The boy said interestedly, “My mother dropped her gold watch down here yesterday.”
The workman's eyes lit up. “Well, boy,” he said, pretending to be careless, “get along with you.”
An hour later the boy came back. “Are you quite sure it was here that your mother lost her watch down?” asked the workman.
“I am certain,” replied the boy with a cunning smile, “because I saw Father get it out with my own eyes.”
