In the afternoon, when I came home from school, I saw grandma bending to pick vegetables. I thought to myself, "grandma must be very tired. Grandma has been taking care of me since she was young, so I can't let Grandma's back bend any more." So I went up to my grandmother and beat her back. She said happily, "you are my good grandson." I feel very happy that I can do something for grandma. In the future, I will often help grandma do something I can.
