Dear Mary,
Yours,

Dear Mary,
Thanks for your invitation. I¡¯d love to go to your birthday party, but I can¡¯t.£¬because I¡¯m too busy. I have too many things to do (next Sunday). I have to clean my room and wash my clothes. And I have to do my schoolwork the whole morning. In the afternoon, I¡¯m going shopping with my mother. In the evening, I have to help my mother do some housework at home. So, you see, I¡¯m really very busy. I¡¯m very sorry. Maybe I can go to your party next time. Thanks for asking. Happy birthday to you! I hope you have a good time!
Yours, Lucy
