In a plain white box as if the inside of a sugar cube could be entered, crystalline; the white of a city made of salt you read about once. Or else somewhat less so, mostly-white, a window here and there, a grey or wooden floor, a desk etc. mar the scene but not irreconcilably so. The walls are not each of the same dimensions, the ceiling is variegated, the light shines unevenly across it all. Or else either of the prior states is augmented – walls are papered, carpet is laid down, lighting is adjusted or turned off altogether. Or else the walls are foregone – the play is outdoors in sand or snow or woods. Or maybe we’re in the round: an operating theatre, no partitions, props maybe, audience on all sides, care needed to avoid eye contact across so evenly distributed a fourth wall.
