Hope you are fine and enjoying yourself in hostel.
We all are worried about you. Please do take proper care of yourself. Avoid eating junk food, take proper food in the mess, sleep on time and don’t waste your time in playing. Study carefully and try to achieve good results.
Mother and father are also worried. We all miss you, but you know studies are very important for a good life. Very soon you will be having your vacations and we will meet. Mother and father have sent their love to you.
