Answer:
Letter writing about an unexpected absence.
Step-by-step explanation:
To,
My dear friend Rick
I hope you are not angry with me. I know I promised to be there to see you awarded by the university. And I am so sorry to miss that. But I have a valid reason for skipping that.
Just a day before your event, my father got a heart attack and we had to get him straight to the hospital. And considering the seriousness of the situation, the doctor has advised us to be admitted for some days just to keep my dad under observation. And with my mother's condition, I am the only one available to stay with him. So, I had to stay there and take care of things. I didn't even get the chance to inform you and I apologize for that.
I will definitely make up for my absence. I only hope that you understand my situation and forgive me. Since we are still in the hospital, I can't go anywhere. But I will visit you soon.
Take care and will see you soon.
Lots of love,
Jackie.
