Hi Mark!

I know that I made you a promise that I’d be in London next week but unfortunately, a week ago, when I was skiing in Slovakia, my passport and all other documents got stolen. In this situation I won’t be able to come to London. I’ve already been in the passport office. My friend works there and he promised to help me get a new passport as soon as possible. I promised to bring him some nice souvenirs from London in return. I hope it won’t be a problem for you if I come in two week’s time. I’m really sorry for this situation. I hope to see you soon.

Don’t be mad at me.

Yours,

XYZ
