Most marriages end a lot sooner than 68 years. That’s what should have happened to this one. Stuff builds up. All kinds of stuff. All that lovey-doveyness dries up quicker than a desert water hole. A marriage is perhaps good for 5 years at most; this tragic one went on for well over a half century longer than that, evidently festering and bubbling up and finally climaxing like exploding pus in an unhealing sore. Marriage, like belief in sky people, is a cruel and inhuman institution.
