Suppose you have accepted Mr. Zhang’s invitation to dinner, but you have to change your plan for some reasons. Write a letter inabout 100 words to make an apology to him.
Dear Mr. Zhang,
I sincerely thank you for inviting me to dinner in your house next Sunday.
However, now, much to my regret that I may not be able to keep my promise because I have just been caught serious cold, which requires me to take a rest for a long time. And I apologize for any inconvenience that may cause you. If I get better during this time, I will be there on time.
I am very sorry for that and really regret that I would miss such an excellent chance of enjoying the perfect dishes with friends. Besides, please give my regards to Mr. and Mrs. Rogers when they come to dinner.
Yours sincerely,
Li Ming
