Thank you for your invitation to dinner at your home tomorrow evening. Unfortunately, it is much to my regret that I cannot join you and your family, because I will be fully occupied then for an important exam coming the day after tomorrow. I feel terribly sorry for missing the chance of such a happy get-together, and I hope that all of you enjoy a good time. Is it possible for you and me to have a private meeting afterward? If so, please don't hesitate to drop me a line about your preferable date. I do long for a pleasant chat with you.
Please allow me to say sorry again.
I am eagerly looking forward to your visit to our city. After all these years of writing to each other, I can not wait to see you. However, I regret to inform you that I will not be able to meet you at the airport on time.
The reason is that your flight will arrive early in the morning, and the earliest I can reach the airport will be about an hour after you land. Will you please wait for me in the arrival lounge? You can have breakfast while you wait.
By the way, as we have never met I must tell you home to identify me: I am of 165cm tall and have a long hair. In addition, I will wear a white skirt and carry a China Daily at hand.
Hope we can meet soon.
I am afraid that you will think me unpardonably negligent in not having answered your letter dated 7, December sooner, but when I have told you the reason, I trust you will be convinced that the neglect was excusable. When your letter arrived, I was just in Hong Kong. As my family could not forward it to me during my absence, it has been, therefore, lying on my desk until the moment when I took it up. Now the first thing I have to hasten to do is to write to you these few lines to express my deep regret.
I enjoyed many pleasant sights during my trip. I shall be pleased to give you an account to of them when I see you next.
