Dear Professor White,
Many thanks for your letter dated 15th August, inviting me to attend and
chair a session of the forthcoming 20xx International Conference on Parallel Data Processing to be held in Bellaire, Michigan, from October 25 to 28, 20xx.
Much to my regret, I shall not be able to honor the invitation because I have been suffering from a disease since this summer. I am firmly advised that it would be unwise to undertake any distant and long travel in the near future.
I feel very sad to miss the opportunity of meeting you and many others in the field of Computer Science. I wish the conference a complete success.
Faithfully your
Dear Jane,
We have four tickets for a famous film shown at Guangming Cinema, The Longest Day, Friday, the ninth. Will you join us? We'll be looking for you at eight sharp Friday night in front of the cinema, so don't disappoint us!
Warmest regards.
Alice
