(Address 地址）November 30, 2010 (注意: 地址与日期都放在最右边) Dear Clarence, I am sorry to inform you that I could not go to Hangzhou this coming Friday. I know that we have already planned for this trip since last month and you must be very disappointed. My mother called me this morning stating that my uncle was involved in an accident last night. We are very worried about him. My mom asked me to accompany her to go to Foshan this afternoon. I hope you may forgive me for my sudden leave. I have no choice but to postpone this trip to next month. Please accept my apology. Thank you. Best Regards,Penny 希望你满意.谢谢.
