有一天，我放学回家的时候，在小区的地上发现一个钱包。我捡起来打开一看，见里面有几十块钱，钱里夹着一张照片，拿出来仔细一看，咦？原来是我的朋友冬冬。后来我就找到冬冬，把钱包还给了他。冬冬握着我的手，真情地说：“真是谢谢你，帮我把钱包捡回来！”我摆摆手说：“不用谢，这是我应该做的！”我真高兴，今天做了一件好事！
One day, when I came home from school, I found a wallet on the floor of the community. I picked it up and opened it. There were dozens of dollars in it. There was a picture in it. Take it out and have a look carefully. Eh? It turned out to be my friend Dong Dong. Then I found Dongdong and gave him my wallet back. Dongdong holds my hand and says sincerely, "thank you so much for picking up my wallet!" I waved and said, "no thanks, this is what I should do!" I'm so happy that I did a good thing today!
