The Still Drain
A pipe runs the length of it at knee height, and you step over its brackets every few paces. It keeps on, straight and tight, for 4 paces. Sand has been tracked along the floor in the shape of a great many boots. Someone has scratched a tally into the wall — 50 marks, the last one shallow, unfinished.
Depth 50.
