Well before sunrise it is completely dark. The stars are out and there is no light in the east. It is night. Morning seems to come with both a gradualness and a suddenness. Light appears in the sky as the sun is moving towards the start of its day. The light spreads out from that point as it gets closer and closer to the time of sunrise. But there is a change in the air. It is as if every molecule of air is crackling as each lights up gradually. And suddenly, they all get to full brightness at the same time and it is light. And now the sun peaks above the horizon.
