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
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 Kate:
Excuse me for my long delaying in returning to you your “robinson crusoe” Which i read through with great interest. I had finished reading the book and was about to return it when my cousin came to see me. Never having seen the book, she was so interested in it that i had to retain it longer. However, i hope that in view of the additional delight thus afforded by your book, you will overlook my negligence in not returning it sooner.
Thanking you again for the loan.
Sincerely yours,
