Their lives were not timelines, but many intertwining threads, stopping and starting on a whim. Every moment could be a start or an end, a little birth or a little death; it happened when they woke up, after orgasm, in the park or in the rain -- a sudden reconfiguration of the world, a reinterpretation of their thoughts and feelings into something completely new. They had personalities made of Lego bricks, and they loved it.
