Subject: Letter about the bad effect of excessive TV watching.
I received a letter from father and came to know that you are now in the habit TV watching. TV watching is good, no doubt. But everything has its limitation. No one should cross this limitation. Excessive TV watching will make you addicted to TV. It will keep you away from study. It will kill your valuable time. Whereas study, study and study is the first and foremost duty of a student. So leaving study you should not watch TV. I want to advise you to watch only educational program if there is any and sometimes news. Dear brother, try to follow my advice. It would be better for you.
Wishing you best of luck
