When I went shopping with my friend Lucy,I lost my wallet in the supermarket.I was worried and looked for it everywhere.But I still couldn't find it.When I wanted to give up and went back home with my friend.I heard there was a sound looking for the loser in the supermarket broadcast.I was very happy and went to the lost and found.It was really my wallet.I was very grateful.If the world has more kind people,it will become more and more beautiful.
