Dear sister,
 I hope this letter finds you in great health and state of mind. In her last letter, dear mother confided to me that you have become very careless and irresponsible. So, l am telling you to take care of your health.
 You don't have any schedule. You should demand fast food regularly. You don't lend any helping hand to mother and your room and cupboard are in perfect disorder. You just sit infront of T.V in wrong posture for hours wasting your precious time. She also told me you have put on more weight. If you continue living like this, where will it lead you? You will have to regret. Dear Shraddha sister kindly take care of yourself. You should make some schedule and stick to it. Life is full of challenges and wrong life-style just adds to these challenges.
 l hope you will eat nutritious diet, do some physical workout, and lend mother some helping hand. Looking forward for your next letter.
 Your loving sister,
 Shreyaa.
Hope this answer helps you. Thank you.
