阅读下面短文，然后按照要求写一篇150个词左右的英语短文。
A few months ago, Peter worked for a short time as a cashier（收银员） at a restaurant. He also helped clear the tables when it was especially busy. One night, just before Christmas, he found a large black wallet on the floor near one of the tables. He guessed he should have checked it for the owner’s identification, but he was very busy at the time. Also, he figured that if the wallet contained anything valuable, the owner would be back. Sure enough, an hour later a man came up to the counter and asked if anyone had found a wallet. Peter asked him to describe the lost wallet and after he had described it exactly, he gave the man the wallet. The man seemed greatly relieved when Peter handed it to him.
The man asked Peter if he had opened it, and when he was told “No”, he at once opened it and revealed nearly $1,000 in cash. He took out a 20-dollar bill and handed it to Peter. Peter pushed it back. “ Bless you for saving my Christmas plans. It’s people like you who make everything in the world look so good.” The man said and then turned and walked away.
