Write a letter to your friend inviting him on the occasion of the marriage ceremony of your elder brother or sister.
30 Bashabo, Dhaka
You will be very glad to know that the marriage ceremony of my elder sister is going to be held on 28 April 2013. I cannot even think of passing the ceremony.
Some of my friends and all the relatives are also invited. My parents tell me to invite you and they will be very glad if you come to our house. If you join us before the day we will have a nice time and we will do many things to make the ceremony successful. We hope you will come to our house before the day.
No more today, we are eagerly waiting for your arrival. My best regards to your parents.
Your loving friend
