Dear David:
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.
Yours sincerely,
Li Ming
Dear Linda,
I am excessively sorry to say that i had failed to keep the appointment that we made last friday. Now, i am writing you this letter of apology to show my deep regret. Please accept my sincere apology. I hope you will understand me and excuse me for my failure to turn up.
The reason for my absence was that my mother fell ill at that time. I had no way out because i had to send her to hospital and look after her. Therefore, it’s not in my power to meet you.
Naturally, i want to suggest that we should make another appointment next time.，i shall be obliged if you will kindly write and tell me when and where you will be at convenience.
We may meet again and i hope to see you soon.
Yours sincerely,
li ming
Dear miss nancy,
Much to my regret i was unable to keep my promise to attend your birthday party last saturday, owing to the fact that my little son was suddenly taken ill early that day.
Hoping to see you soon.
Truly yours,
Tom
