My dear Rashmi,
I received your letter yesterday. Glad to know that you have topped in the half-yearly examination. It is a matter of pleasure, but I feel sad to know that you have grown physically weak. This is not good at all. You should spend at least two hours in the field.
You know well that ‘All work and no play make Jack a dull boy’. I would sincerely advise you to spare some time for physical exercise. You can enjoy badminton. Don’t forget that in a healthy body a healthy mind resides.
With best wishes
