Dear Joe and Sue,
I saw the announcement of your wedding in the Grand Rapids Press. Congratulations! That is great news. I am sending along a copy to my parents, who will remember my talking about you when we were in college together and worked at the same bank.
You are great people and I wish you all the best!
Robert "RJ" Regan
