They have had separate bedrooms for the last ten years at least. But I liked to imagine that sometimes late at night their drunken stupor would leave their lonely minds wondering and they would tiptoe into the darkened bedroom of their reticent life partner, and touch their skin. For the the first time in too long. And they would lay with their faces together and whisper, "What the hell are we doing?" Three adult children, and still children themselves. And they would laugh instead of scream. And in the black of three AM they could be honest with each other. And every once in a great while they could remember that they understand each other.
But I don't know that this ever happens. Maybe they haven't been friends in years.
