Dear John,
I am extremely sorry to tell you that I am unable to go to your party on this Sunday. It is very
kind for you to invite me to your house and I really look forward to going to your party and share
your happy experience abroad. Manny to my regret, I will be absent from your party owing to the
fact that the College Entrance Exam is just around corner, for which I am now really busy preparing.
What's more, I have caught a bad cold lately and I was really not myself.
Anyway, we will have many more chances to get together. Shall we make it after the Exam?
I am true sorry. I hope you will forgive me and receive my sincere apologies. I look forward to
your reply.
Yours truly,
Li Hua
