 It's an accounting of life that takes as long as life itself. We both step and do not step in the same rivers. We are and are not. So said Heraclitus, and so say the sisters as they move in and out of shot, catching the flow of things, framing themselves for a moment as they are and as they are not. Personally, I am moved by their industry. No one's paying them for their labor, yet this doesn't deter them.
