When Sally stopped crying, she found herself alone, the cold draft of the window at her neck, and on both sides, the rows of doors went on and on, diminishing to nothing, the end. 'What fun it is to ride and sing a sleighing song tonight, oh.' What glories.Mathilde came. And though she appeared to be the... same sweet girl Sally had been afraid of, she was not. Sally saw the flint in her. Mathilde can save Lotto from his own laziness, Sally thought. But here they were, a year later, and he was still ordinary. The chorus caught in her throat. A stranger hurrying as fast as he could over the icy sidewalks looked in. He saw a circle of singing people bathed in the clean, white light from a tree, and his heart did a soumersault. And the image stayed with him, it merged with him even as he came home to his own children, who were already asleep in their beds, to his wife crossly putting together the tricycle without the screwdriver he'd run out to borrow. It remained long after his children ripped open their gifts and abandoned their toys and puddles of paper and grew too old for them and left their house and parents and childhoods, so that he and his wife gaped at each other in bewilderment as to how it had happened so terribly swiftly. All those years, the singers in the soft light in the basement apartment crystalized in his mind, became the very idea of what happiness should look like.
