Today is Mother’s Day. I know some of my classmates are going to help their mothers with the housework, others .are going to buy some flowers for their mothers. I want to say to her that I love her very much. But as a boy, it is a bit difficult for me to show my heart. I think only girls can do that.
My mother is very kind. She takes care of me day and night.
She spends little money, but buys anything for me that I need.
This time I must show my love. I am going to give her a card and write like this, "I love you, mother!" I am going to put it under her pillow.
