A Young Woman Falls In Love With Everything

Sunday, May 25, 2014

You start with difference, with mystery. Some things spiral, some become spheres, some branch, some don't. We know that inert atoms quicken, become bees, goats, clouds, then dissolve back into randomness. We look at these things, all these very, very different things, and we wonder, are they really different, or ...
