Hi Coco,
Thank you for your invitation. I’m sorry I can’t visit you this week. I am really busy. On Saturday, October 20，2012. I am helping my mom do housework and doing my homework . And in the afternoon, I’m going shopping with my friends. And tomorrow, I have to visit my grandparents. Yuck! On Sunday evening, I have to go to school for a test.
Write soon
