A Letter of Declination
Dear Angelo,
I"m obliged to you for inviting me to attend your birthday party to be held on Jan. 20. I would like to accept your warm invitation but I"m afraid I cannot due to an earlier appointment.
One month ago, l made an appointment with one of my high-school classmates. She will accompany her father who suffers from diabetes to Beijing to see a doctor. Since she is not quite familiar with Beijing, she asked me for help and I have consented.
Anyway, I feel sorry for disappointing you. However, please expect to receive my pleasantly surprising gift for you by EMS on your birthday. Happiness, health and good fortune will all come and belong to you on this golden day!
Sincerely yours,
Li Ming
