The first one to bed always lit the candle, and the last one turned out the lamp....The tradition had seen them through quite a bit by now, and Rebecca had come to love the candlelight, not only because it meant that Mike loved to see her just the way she was, which was incredibly liberating once you began to actually believe it, but also because the light just felt holy to her. It made the end of the day into a kind of prayer, whether they made love or just lay in each other's arms and chewed over the day's portion of craziness; and there was that beautiful little puff of Amen when they blew the candle out and settled into sleep.
