This afternoon, I was walking in the street when I caught sight of the lady before me drop her purse.

Just as I was to remind her, she got into a taxi and went away. I picked it up, trying to find some information to contact the lady. But with no telephone number inside it，  I decided to wait for the lady, in case she found her purse missing and would come back. But to my disappointment, half an hour passed, and the lady didn’t show up. As a consequence, I had to walked into the nearest police station, where I handed the purse to a policeman, who said he would try to return it to its owner.

       I was happy because I did a meaningful thing. I think it is our duty to help those who need help. Only in this way will our society become more harmonious.
