" Sugar understood the permanence of being Sugar or Lotty or Lucy or whoever you might be, trapped on a square of card to be shown at will to strangers. Whatever violations she routinely submits to in the privacy of bedroom, they vanish the moment they're over, half-forgotten with the drying of sweat. But to be chemically fixed in time and passed hand to hand forever: that is a nakedness which can never be clothed again "
