Love, to her, was something that comes suddenly, like a blinding flash of lightning- a heaven sent storm hurled into life, uprooting it, sweeping every will before it like a leaf, engulfing all feelings. It never occurred to her that if the drainpipes of a house are clogged, the rain may collect in pools on the roof; and she suspected no danger until suddenly she discovered a crack in the wall."
