Directions 9
Suppose you cannot attend your sisters graduation ceremony as expected for some reason. Write a letter in about 100 words to make an apology to her. Do not sign your own name at the end of your letter, using Li Ming instead.
Sample:
Dear Linda,
Kindly excuse me for my not being able to attend your graduation ceremony next Wednesday as I have promised.
You know, there will be a meeting of great importance to my company next week in Nanjing. But the person who was originally appointed to it is now seriously ill in hospital. And I have been asked to take his place to attend the meeting and make a speech on behalf of my company. On the one hand, it is a task assigned by my boss out of his trust in me. On the other hand, I do regard it as an opportunity to both display and enhance my abilities. So I am afraid I cannot be present at your graduation ceremony.
Though I have decided to send you a gift to celebrate your graduation, I really regret that I cannot give you my sincere congratulations on the spot, for I know any gift can never parallel a warm word spoken personally by a family member. I do feel terribly sorry. Please forgive me.
Cordially,
Li Ming
