Dear Sir or Madam,
I’m writing this letter to apologize to you. I’m so sorry that we made a mistake about the shipment of vacuum cleaners.
Those vacuum cleaners we sent to you were meant to be sent to European countries, but as the old worker was retired, the new one wasn’t so experienced. Besides, the model number and the price of goods in March and July are so similar that the worker mistaken them.
I am awfully sorry for this and we promise you a replacement shipment. We will also give a 10% discount to compensate.
I do apologize for any inconvenience this may cause you and I will try my best to avoid the same accident happening again.
Yours，
Eva
Dear John,
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.
Sincerely yours,
Alice
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.
Sincerely yours,
