But you keep it there in your mind. Even if you never take yourself up on it, it gives you a kind of comfort to know that the day is yours to choose. You tuck it away in your brain like sour candy tucked in your cheek, and the puckering memory it leaves behind, the rough pleasure of running your tongue over its strange terrain, is exactly the same. The day was hers to choose, and perhaps in that treetop moment when she looked down and saw the yard, the world, her life, spread out below her, perhaps she chose to plunge toward it headlong. Perhaps she saw before her a lifetime of walking on the ruined earth and chose instead a single moment in the air.
