It is very hot and wet today. When my mom did the cooking in the kitchen， I saw her head was sweaty and she was a little bit tired. I told her I could help her to make the dinner and she accepted. But all I could do is washing the food and bringing something to her. After cooking， we were all sweaty. However， my mother and I all felt happy. She said that I have grown up and become her good assistant. I thought I was a good child of my mother.
