English composition of bus fun

An interesting thing One day, my mother and I went to the park. We had a good time, and we decided to have lunch in the park. My mother bought some milk and bread. My mother told me to wash my hands before lunch. However, when we came back, our bread was gone! We think someone took it. We are very angry. I thought the thief would come back for the milk. So, my mother and I waited behind a tree. An hour later, no one came and we were very hungry. We gave up. We wanted to go home and get something to eat. Suddenly, I found something under the chair. Oh, this is our bread!
