Dear William,
Thank you so much for your invitation to your birthday party this Sunday evening. I'd love to come, but I am afraid I cannot make it. I will leave for Beijing on a business trip the day after tomorrow. And I will have to stay in Beijing for several days. So I am afraid I will not be able to come back until next Monday. Please say hi to all our friends. I wish you all a good time!
Happy Birthday!
All the best,
Jim
