" You think you know the story so well. It’s a mansion inside your head, each room just waiting to be described, but pretty much every memoirist I’ve ever talked to finds the walls of such rooms changing shape around her. There are shattering earthquakes, tectonic-plate-type shifts. Or it’s like memory is a snow globe that invariably gets shaken so as to shroud the events inside. "
