I nearly help my mother to do the housework, when I go home after school, I always go out to play with my friend and then until the dinner, I will come back. Now as I grow up, I start to realize that I need to help my mother, I should share some housework, so that I can reduce her burden. Since I help my mother with the housework, she looks so happy, she will praise me in front of her friends. I feel proud of myself.
