Every time I finish my homework, I go into the kitchen and ask my mother what I can do to help her. I often pick vegetables, wash vegetables, wash fruits, arrange dishes, prepare rice... When my mother needs sugar, salt or seasoning powder, I will also help her find it. Mother and I have a lot of fun cooking. My mother praises me for being good because I know how to help her cook. I really like that.
