Supongamos que alguien nos invita a un evento y nosotros no podemos asistir. Lo correcto es escribir una carta de agradecimiento y disculpas. Lo más importante es saber distinguir si debemos escribir la carta en tono formal o informal, dado que las expresiones y conjugaciones cambian sustancialmente. Veamos a continuación dos ejemplos:
Thanks for your invitation to your party on Thursday. Sorry, but I can´t make it. My boss has just let me know that I have to go on a training course in Birmingham from Monday to Friday. As you can imagine, I´m really fed up about it. I was really looking forward to seeing all my old mates again. I´ll ring you for a chat when I´m back. Say “hi” to everyone.
Dear Ms Smith
I am sorry to inform you that I shall not be able to attend the interview that was arranged for next Wednesday. This is due to a staff shortage at work. All full-time employees have been requested to be at work every day next week. I should make it clear that I am still very interested in the job I have applied for in your company and I would be most grateful if a new interview date could be arranged. I apologize for any inconvenience that this causes you.
