Respected father,
I am in receipt of your kind letter. Thanks for the same.
I am surprised to learn that you will be away for another week. Respected mother has not yet recovered from her illness. The doctor is paying visits every evening. It will take her a few days more to get normal. She is taking the medicines prescribed by the doctor. I would be happy if you could finish your job as soon as possible and be there besides, mama, so that she can recover soon. I will be there soon after my exams are over.
I have taken up my studies more seriously. I hope I shall do well in the coming examination. You should not be anxious about my studies. I am doing my best.
With best wishes from all of us.
Yours loving Son,
