    Today is Mother's Day. I love mother so much that I've done many things for him. In the morning I buy some flowers with my pocket money and put them in a vase. In the afternoon, I went to buy some vegetable and cooked simple but delicious dinner for my family. After the meal, I gave mother a card what I made myself and said “Happy Mother's Day” to her. Then I told her to pay more attention on her health and not overwork. I also promised to help her to do some housework from today on. Heard the words, mother was moved to tears.

    Today is a specially day, warm but meaningful.
