(Body of the letter)
Well and wish the same from you. I am sure you have done pretty well in your Summative Examinations. Here, I have done my Papers well. I am satisfied with my performance and I expect a good score with distinction.
My summer vacation starts at 18 May 2015 and our College reopens on 16 June only. We plan to go on a tour to Kanyakumari on the 20^th May morning and return back on the 22^nd May morning. If you have no other programme, please join us. It would be really a fun and I will be happy to spend a week’s time with you during the vacation. My parents will talk to your mother if you are willing to join us. We shall feel honoured if you come over here and spend a week with us. My parents and I are eagerly waiting for your arrival and stay with us.
Convey my regards to your family members and kids. Awaiting your positive reply. (Subscription) Yours lovingly
