Right now I have the computer's screen and my kitchen light on. There is also light coming in from my balcony window. But, not that long ago, It was daylight, lanterns and candles. Before that, it was a camp fire and a spark on the end of a stick. Earlier still, it was only the moon and stars.

Light and Dark
Are you afraid of the dark? Have you ever been?
Now, feel around you. Someone warm is here to hold you. It is pitch dark and raining for hours on end. It was dark all day. It is dark all night. A child's fright. A child who has only known day's light. Mother is near, out of sight. Now shiver. Hear rain hit the world all around. They sound like foot steps to a child's mind. The smell of mud and sweat and dust and your mother's hair. Now, ever quieter, ever more, in dreams, like the dancing of some pleasure at arm's reach, just as you slip beneath the rain and your mother's arm to the land of sleep, the brightest thing you have ever seen flashes every shadow in the universe brilliant, yet unseen. All shapes and shadows and hard burning lines. Then the loudest thing you have ever heard in your young life, the sound felt as much in the bones as in the ears, grabs you and shakes you back a wake. Your mother shook too. What could scare her? What is that terrible?
