You will be very glad to know that the marriage ceremony of my elder sister is going to be held on 9th September, 2015. My parents asked me to invite you and your family members. So, I cordially invite you all to attend the function and make it a happy moment for all of us. My parents desire to see you all in our family one day before commencing the function at our home. We are eagerly waiting for your arrival.
