Subject: Requesting to attend the marriage ceremony.
My Dear John,
The marriage ceremony of my elder sister, Mahmuda, is going to be held on Friday, the 30th instant. So I shall be very glad to have you in our midst on this happy occasion. My parents also expect you in our midst very much. The bridegroom’s party will reach our house at 7:00 PM on the 30th. I should, therefore, request you to come to our house at least a day before the said party reaches our house. We shall be very happy to have you with us and we shall be very sorry if you fail to turn up at the right time.
More when we shall meet together. I am eagerly awaiting your arrival in time.
