 Even if you don't move, you will get somewhere and then return to wherever you started. And if we may speak of the depth of a metaphor, well then, it's about three feet deep. Excepting a brief stretch at which point it rises to six feet four. Here, children scream, clinging to the walls or the nearest adult until it's three feet deep once more. Round and round we go. All life is in here, flowing, flowing.
