A friend asks of a photo I've taken, is that up or down? I don't really know or have forgotten, having sent him the photo a couple of days ago. He's in Berlin, I'm in Wyoming. Perhaps the photo flip-flopped on its way overseas. I don't know. I should say, it's Heraclitean, Fred, up is down and down is up. He'd understand. And down below on the plain beneath the tree, Fred, is the same river you can't step in twice.
