You were supposed to receive a friend at the airport. But, for some reasons you are unable to do so. Write a letter to your friend. In your letter
– explain why you can’t come,
– guide them regarding other options to get to your home,
– describe the plans/visits you made to show them around when your friend arrives.
I believe your preparations to come to India are in full swing. I am eagerly waiting to see you on Thursday evening. As discussed earlier, I had promised to collect you from the airport but unfortunately I would not be able to keep my words due to an unplanned official meeting.
Just yesterday my boss informed me about an urgent meeting of foreign delegates that will take place on the coming Thursday, the day of your arrival. I have been asked to give a presentation too. In this case, it won’t possible for me to reach the airport as we had planned earlier. Don’t worry. The airport has an excellent taxi service. My suggestion for you would be to take a cab from the airport to reach my home. You can book a cab online or hire one from outside the airport.
I just can’t wait to see you and I have planned many things for your stay. I have reserved seats for a get-together with our college friends in the ‘Memories Café on Friday evening. On Saturday, we would go shopping and enjoy the street food of Delhi. We will plan the rest of days as per your preferences.
I Look forward to seeing you soon!
