Dear Charlie,
Kindly excuse me for my not being able to see you off at the airport this Saturday as I have promised.
A major business partner of our company will be attending an important conference in Xiamen this weekend, and my boss finally chooses me to accompany him there to negotiate about a new transaction. I have just been informed of this plan and am happy about the decisionthis is an opportunity to both display and enhance my abilities, so I am afraid I cannot be present at the airport.
Pursuing study overseas is an essential step in the accomplishment of your dream. How I wish I could have the chance to share with you my personal feelings and suggestions before you are away! I hereby send you a gift to wish you good luck. Please forgive me.
Cordially,
Li Ming
