道歉信范文一
Dear Mary,
I’m very sorry for not having replied to your July 6th letter sooner. When your letter arrived, I was in Beijing. As my secretary couldn’t forward it to me, it has been lying on my desk until I got back.
Thank you for all your news. It is good to know that your company has agreed to sign the contract to continue the cooperation with us. And we surely will have a bigger success in the near future.
Look forward to catching up and once again apologize for the delay.
Sincerely,
Tom
道歉信范文二
Dear Susan,
I’m very sorry that I was out when you came to see me yesterday evening. I’m afraid I’d gone to the pub with some friends and didn’t get back until 12 o’clock. I wish I had known you were in Luoyang as you could have come with us. It would have been a good introduction to the night life!
Anyway, I will call on you at 10 o’clock on Saturday morning at your hotel. We can have the day together, if you have nothing else planned? I’ll show you some of the places of interest that you may not have seen.
Please let me know if you will be available on Saturday morning.
Best wishes
Chen Cheng
