Dear Jai
Congratulations! I have just received the invitation to attend your wedding. I was thrilled to get this news, and even happier to know that the girl you are marrying was with us in school. I have been trying my best to remember what she looked like.
I regret it will not be possible for me to attend your wedding, much as I want to, for I will not be able to get leave from my office.
Do send me photographs.
Wishing you a very, very happy married life.
With lots of love
Yours ever
Geeta
