Today, I came home from school and found the ground dirty. I think it must be that mom and dad are too busy with their work. I went to the kitchen to get a broom and came to the living room. I immediately started sweeping the floor, first from the right to the left, and then from the bedroom to the living room. I saw it again. I felt it was clean and spotless. When mom came back, she was shocked. My mother asked me, "who swept the floor so clean?" I smiled and said, "who else is there besides me?" Mom is happy to say that you are a hard-working child. After being praised by my mother, I feel very happy!
