228, Lovely House,
I know you must be desperately trying to contact me. Actually my phone is not reachable as I have come to my native place. My father is ill and has just gone through a minor heart attack. I just got a call from my mother in the office and I had to catch the earliest train to my native place to rush there.
Now my father is fine as he was hospitalized for two days. I need to tell you one more important thing. As my father just escaped with an attack my parents are forcing me to get married with a girl who is staying here. She is just our next door neighbor over here.
I tried convincing them but all in vain. I will have to get married to her taking consideration to my father’s illness.
I had to accept the proposal and so am writing this letter. Please forgive me for this. I could not help it. Try to forget the times we spent together.
