Dear John,
I am very sorry to tell you that I unable to go to your party this Sunday. It is very kind for you to invite me to your house. I really look forward to go to your party and sharing your happy experiences abroad. Much to my regret I would be absent from your party because the final exam is just in the corner. What's worst, I have caught a bad cold lately and I am really not me. Anyway, we will have much more chances to get together. I am true sorry. I hope you will forgive me but accept my sincere apology.
I am looking forward to your reply.

Yours,
