如果您跟人家約好去做某些事情，但是你卻失約了，這個需要向人家道歉，説明原因，興許還能得到原諒，下面是關於失約道歉信，希望對您有幫助!
Dear Alan,
I'm writing to apologize about last Thursday.
I am terribly sorry that I didn't go to see you, for I lost my wallet.
Anyway, I found it.
But it was too late for the train.
I had to take the bus.
What a pity that I took a wrong one.
It went to Milford.
There, I waited for half an hour for a bus to Driffield.
It was much worse that on the way to your home, the bus broke down.
So I just went back home to Pigston.
I really do apologize because I didn't speak to you on the phone, but it wasn't my fault.
I tried several times, but there was no answer.
Anyway, how about next Thursday?
Love,
Tom
女友:
今天發生了一些不愉快的事情。
你説自己幹嘛回家後非要再去那裏瞎逛，逛就逛吧，為什麼要到那時候説你去過那裏。你自己答應的事情忘記了嗎?非要別人每天每時每刻都去提醒你嗎?豬腦子嗎?一定要記得!!!不準有以後!!!
你要記住這是你自己做出的承諾，既然你已經做出了承諾，答應過別人的事情，就一定要做到，要不然會讓人心寒，又會讓人受傷。
昨天你對我説的那些話讓我心裏十分難過，我也自己反省了一下自己，確實這樣做這件事情十分的不對，因為我沒有做到答應過你的事情，我如果當時告訴你了也許就不會有這些不高興，也不會傷到你了，本來昨天是高高興興的一天，然而卻毀在了我的'手裏。
我知道，一句對不起不可能一下就能撫平對你所造成的傷害，所以我現在需要做的事情就是用實際行動去改變一切。做一個不會再去傷害別人的人。如果再做出這樣的事情來，就真的豬都不如了。
希望你在看到這一封道歉信的時候，能夠不再生氣，能夠快快樂樂的。也希望你能原諒我這個昨天有些混蛋的我。
