Dear Mr. Singh
I am writing this letter to apologize for the last meeting that I could not attend.
The reason for not attending the meeting was that my father had a heart attack. My brother and I had to take him to the hospital immediately.
I was very stressed that I forgot about the meeting and also to inform you about that. I really apologize for that and I will take care of that from next time.
I hope you understand my emergency and accept my apology.
Yours sincerely
Mukesh
