I did a great thing in the winter holiday.One day,I was going to the book store and suddenly I found a paper money which worth 100 RMB.I looked around and picked it up.At first,I wanted to use it and I can save my own money.However,I thought a lot and I decided to wait for the person who lost the money at last.10 mintues later,a little boy who was anxious came towards me and asked me if I had picked up 100 yuan.I handed the money to him and he was surprised to get the money back.I was very happy when he said "thank you" to me.then I went back home with a big smile.嗯~不错就你了
