I don't know about fifty. The issue never arose at that time. I fell in love with Mrs. Murphy when I was twenty-two and I'm still falling. I haven't bottomed out yet.
We've been married for fifty-three years and the training period (for both of us)took fifty-two years and eleven months. We have shared our thoughts on this subject and neither one of us would go again if something happened to the other. It's simple. Why in HELL would anyone want to start over at this stage of the game?
I think the answer is that everyone's entitled to one good marriage. If you've had it, be satisfied. If not, go for it.
Love and Lilac Blossoms, Spud
