This is Harry on the other side talking to you. You may be wondering as to why I am talking in this way; but since I have not been able to convey you my thoughts confronting you, I thought this letter shall serve my purpose.
Mom, the thing is; you have been losing your grip on your health in the recent times. I am really concerned about your health. You have started to get deteriorate on the health grounds and you have even started losing temper very often. This is what has urged me to write to you. Mom, you are the pillar of this home and anything of this sort shall affect the entire family. I appeal you to take care of your health. If anything is bothering or irking you, please let me know. I hope this letter conveys my concern and appeal for your health in the right context.
Your caring son,
