Dear Andrew Hall,
Many thanks for letting me know about your engagement, congratulations are certainly in order. It seems like only yesterday that Colin and I first saw you two out together. It certainly looked like true love even in those early days.
We wish you a long and loving marriage together.
Sincerely,
Riachard
