Rest in Peace.....while that's a very proper, positive, and just plain nice to say, I'm going to deviate a little.
RC took the best care he could of the love of his life, and even more, if that were possible, after she became an Alzheimer's patient. He knew she would deteriorate and die from it.
I'm of the opinion (its what I believe) that God did them both a favor (maybe even answering his prayers) allowing him to pass on first. Rest in peace? That's not the RC I knew. I'm betting he's busy as he can be "preparing a place" for her when it's her turn to pass on.
I believe families can be forever.....if they want to be. I would give anything to see her face, when she passes, and she finds that the person on the other side waiting to greet her is RC!
What a grand finale to this world! And a grand beginning to the eternities to come! "Well done, [RC], thou good and faithful servant."
