十三、My father is 35 years old. His birthday is on the twenty - first of July. On his birthday, he usually has a big lunch with my mother and me. I make a card for him. My mother is 35 too. Her birthday is on the twelfth of August. She usually puts on new clothes on that day. She eats some noodles and a birthday cake. I usually buy some flowers for her on her birthday.
