Write a letter to your friend apologizing for not having kept an appointment.
June 25, 20…..
Mr dear Harjinder,
I am really sorry for not having kept an appointment with you. I had promised to attend your birthday party. But I could not join you. I think you will be annoyed with me. I hope you will excuse me if you listen to me.
I was all ready to leave for your place. Hardly had I stepped out when my left foot slipped. I fell down. My left ankle was dislocated and my left arm was badly injured. I had to be removed to the hospital. I stayed there two days. My left arm is in plaster. I could not inform you earlier. I am sorry for it.
I would have loved to be with you. But now you know that there was a reason behind my absence from the party. I hope you would no longer be annoyed with me.
With best wishes,
