Clouds.

This time tomorrow where will we be? On a spaceship somewhere sailing across an empty sea? This time tomorrow what will we know? Will we still be here watching an in-flight movie show? I'll leave the sun behind me and watch the clouds as they sadly pass me by. Seven miles below me I can see the world and it ain't so big at all.  This time tomorrow what will we see? Fields full of houses, endless rows of crowded streets. I don't know where I'm going, I don't want to see, I feel the world below me looking up at me. Leave the sun behind me, and watch the clouds as they sadly pass me by. And I'm in perpetual motion and the world below doesn't matter much to me.
