Four strangers in a silent waiting room, trying not to meet each other's eyes. Accidents will happen. The passing of trains has as much relevance to this place as the passing of time. Which is to say it only an excuse. Which is to say there are five dimensions: length, breadth, height, long ago and far away.
You use your chair as a ladder. climb up to where the window looks back at you, looks through you. The others watch you as though you were a clock.
The appointed hour is late. You go down to the station bar, order yourself a sonata. You come back shaken. No one else has stirred.
