Dear Mum,
Today I'm going to tell you something really special. I know you work very hard and feel tired every day.
Every time you come home and see the messy house, I know you are very angry with me. But you always say nothing and clean up the house. I feel like dying. I really want to help you, but I'm so tired, too.
I also want to tell you one thing- I love you so much. I usually talk back to you when you say that I don't study hard enough. But in fact I just want you to praise me more. I will try my best to get good grades and get praise from my teacher. So don't feel frustrated(挫败) about my grades, OK?
I have made up my mind that I will have my homework done faster so that I can have more energy to clean the house. I will watch TV less so that I can have more time to study and get good grades. All these things are for one reason—I want to make you a happy mum.
I love you!
Yours,
Sally
