My dear Shashi,
My schools are going to close from 12th of May for the Summer vacation. Yesterday I was talking to my parents about you. They asked me to invite you for this summer vacation. Make your programme and write to me when are you coming? We shall go to Hazaribagh and enjoy few days there also.
I hope your parents will not disappoint me.
I am eagerly waiting for you.
Yours very sincerely
