Apology Letters. Письмо-извинение.
I can't tell you how sorry I am for missing our meeting at the station. My boss wanted me to do an errand for him at the last minute and I had to get it done pronto!
I hope I could make it up to you on another day, maybe we could have coffee? Can we meet up on Friday at 7 o'clock?
Thank you for your understanding and patience. I look forward to seeing you soon.
I can't tell you how sorry I am for missing our appointment at [location]. A family emergency came up which needed my immediate attention. It would be better if I explain the details in person.
I hope I could make it up to you this [insert date]?
Thank you for your understanding and I can't wait to see you soon
