I remember once on my birthday, you cooked a lot of delicious food, bought a big cake and gave me a birthday present. However, you never have a birthday. Buy yourself a birthday cake. Only on my birthday can you eat some birthday cakes. I ate better on my birthday than on New Year's Day, but you never mentioned your birthday. Every time we ask you your birthday, you deliberately change the subject and don't say when your birthday is. So I peeked at your ID card these days. Today is April 8. This year is already late. But next year, I must make you a meal and give you a big gift. That's what I repay you with good grades. I will prepare from now on and study hard. Three years later, I will be admitted to a good high school and a good university to make you happy, proud and proud of me. I'm in the learning stage now, and I can't repay you. I must give you this gift, my great and selfless mother.
