Suppose that you have a friend who is a bookworm. Write a letter to your friend, persuading him to take part in the games.
My dear Sougata,
Recently, I received a letter from Goutam who informed me that you have become a bookworm. You do not take part in physical exercise, so much so that you do not even go for a morning walk. I am really very much pained to learn all this. You know that all work and no play make Jack a dull boy. You are trying heart and soul to secure high marks and a scholarship. It will really be creditable on your part. But at the same time, you should not underestimate the importance of physical fitness. Health is the most valuable gift offered to man by God. Its proper maintenance is very necessary.
I would sincerely advise you to devote some time to games. Actually, this will not be a waste of time. Rather, this would nourish your brain and you will feel afresh for hard work.
I do hope that you will pay heed to my advice and start participating in games.
With best wishes,
Name + Address
of your friend.
