丢失的钱包 Lost Purse

A lady lost her handbag. It was found by an honest little boy and returned to her. Looking in her purse, she commented1, Hmmm.... That's funny. When I lost my bag there was a $20 bill in it. Now there are twenty $1 bills.
The boy quickly replied, That's right, lady. The last time I found a lady's purse, she didn't have any change for a reward2.

一个女性丢了手提包，有一个诚实的孩子捡到后交还给了她。她看了看钱包，说：嗯，这么有趣，我丢的时候里面是一张20USD，目前成了20张一USD。
没错，夫人。小孩子立刻回答道，上次我捡到钱包时，那位夫人没零钱奖赏给我。
