One day I was walking with my mom out of a supermarket then I found a wallet and picking it up. We were on our ways to the parking lot. In front of us were a lady, who seemed to be looking for something and we asked her what she was looking for. She said she has lost her wallet. I asked her if one I picked up was hers. Saw the wallet, she said yes. So I gave it back to her. She was so glad that she insisted on giving me 100 yuan for return. I refused. She was gratefully to us. I returned back home with delight.
