The raccoon-eyed, sparrow-like Rose Byrne is a melancholy figure, to me representing the kind of girl I am on the days when I feel particularly downtrodden by the world, or lacking in vital nourishment (sleep, love, serotonin!), wanting to burrow deep beneath my doona until that feisty little Pollyanna within breaks free of the glum and gets up, gets dressed and sets about... doing the dishes.
