When a boy was taking his father’s meal to the factory, he stopped for a moment to watch a workman cleaning the sewer ( 下水道 ).
The boy said interestedly,” My mother dropped her gold watch down here yesterday.”
The workman’s eyes became wide. “ Well, my boy,” he said. “ Get along with you.”
An hour later, the boy came back. “ Are you quite sure there was a gold watch here?” Asked the workman.
“I’m quite sure.” Answered the boy with a smile. “ Because I saw my father got it out. I saw it with my own eyes.”
