① 小错道歉 April 20, 2010
Dear Peter,
I am writing to you to apologize for the abrupt way I departed just after the exams finished. It was terribly rude of me to have left without saying good-bye to you. The fact is that I was so excited when I learned I had passed the exams with high marks that I couldn’t wait to get home and tell my parents. I am sure you will understand my feelings. Please accept my sincere apology, and with you a really happy holiday.
Yours Truthfully,
Fiona

② 约会取消的道歉 April 20, 2010
Dear Fiona,
I am sorry I missed seeing you yesterday. I know that you must have been disappointed. I also feel worried and anxious in my heart. The fact is that my manager at the last moment asked me to prepare an urgent plan while I could not get to a phone to call you and yesterday I have worked late until about 8:30 p. m. I am terribly sorry. However, I would like to ask you out this weekend to make up for yesterday.
Please give me a chance and I am waiting for your reply.
Sincerely Yours,
Amelia

I imagine that you must be enjoying your birthday party today. I write this letter to offer my heartiest congratulations and best wishes for many returns of the day. It is a great pity that I cannot be with you. But remember I am thinking of you all the time. I hope that all your years to come will be twice as happy and as merry as those past.
