“Dear Mr. Richards,
I am really sorry that I took your money, that I was supposed to use to help your friend Jyoti. I am trying to compensate, I will get her married to my nephew, he really loves her and she is a nice girl.
To ensure that this time I have kept my side of bargain I will invite you to their marriage. But give the lovebirds some time to decide.
I will do my bit to convince Jyoti.
