– Suggest what to do with your ticket.
I’m writing to you about the concert that we planned to watch together this weekend.
I’ll not be able to accompany you to Saturday night’s show. We are a big fan of Shakespear’s stories, and it is the best opportunity for us to watch the performance of theatre artists in our locality. Please apologize for this inconvenience.
Unfortunately, my uncle had a heart attack yesterday night, and I had to take him to the hospital. I have to be with him at the hospital until my cousin arrives. He lives abroad, and he promised to come here within a few days.
I think you and Mike go to watch this show, and he also loves live performances of artists. He has depth knowledge about the stage performances. Moreover, He is a lively person, and you will not feel bored with him.
I hope you both will enjoy this theatre performance.
All the best,
