Two Rays of Serendipity

She's the first ray of light at first light The warmth that reliefs the cold air of night I'm the last ray at dusk to strike And usher in the dark We're as different as fire and ice And as opposite as sunset and sunrise Our minds meet briefly at a tangent And our hearts greet as they depart We replay the joyful moments we have Because together we're killer bees in a hive We seem to find a reason to love, to fight So that we can have a reason to reunite Our love mimics the moon as it tugs at the earth And the earth as it pulls it along its path We're cosmic rays of the same source Waves of synergy on the same collision course
