Dear Nikki
I am so happy to hear of your engagement to Matt. I must confess though, it is not a surprise. When I had lunch with both of you recently, I could see that you made a wonderful couple. I knew it was only a matter of time before the two of you decided to make it a lifetime commitment.
Please keep me up to date on all your plans and pass on my regards to Matt and both of your families. I know he realizes how fortunate he is as I am sure you are aware of what a good man he seems to be.
Sincerely
