My wife, my Mary, goes to her sleep the way you would close the door of a closet. So many times I have watched her with envy. Her lovely body squirms a moment as though she fitted herself into a cocoon. She sighs once and at the end of it her eyes close and her lips, untroubled, fall into that wise and remote smile of the Ancient Greek gods. She smiles all night in her sleep, her breath purrs in her throat, not a snore, a kitten's purr... She loves to sleep and sleep welcomes her.
