Dear May,
Thanks for your invitation, but I'm so sorry, I can't go to your birthday party, because I was too busy. The teacher assigned a lot of homework, in the morning, I must finish my homework. After that, I have to look after my younger sister, until my mother came back. After lunch, I want to help my mother with the housework, such as: washing dishes, mopping the floor...... Long time did not go home to see my grandparents, so in the afternoon, I have to go home to visit my grandparents with my parents and my sister. In the evening, our family stay in the public eat dinner. After dinner, we watched TV together, go home until eight.
In order to express my apology, would you please go to the cinema on Sunday afternoon, I hope you won't refuse.
