Dear Peter,
How is everything going with you?
Thank you so much for inviting me to your weekend party on Friday evening. However, I'm afraid I won't be able to attend it, because I'm now on a business trip in Nanjing. And I won't be back until this Saturday evening.I feel really sorry that I can't join you this time. But I'd like to visit you when I go back from Nanjing. Please let me know what time suits you best.
Wish you a good time on Friday and look forward to seeing you soon!
Yours,
Li Hua
