Flash, flicker, flash, cut to black. We’re watching grainy film of men walking in and out of the stalls in a West German public toilet, casting glances at each other, maybe a fumbling feel; a reverse angle shows us the camera behind the mirror. The men can’t see it, but some of them must surely guess it’s there and defy the odds anyway. Because without defiance, without desire, what are they? Without those things, they know they will only ever be half-alive.
