I walk down to the quayside, past the Pure Gym fitness centre's plate glass window. There is a phalanx of treadmills facing the glass, populated by women running nowhere, an image of futility, trapped like flies at a window, determined and doomed.
The fitness centre looks out at the huge boats that work North Sea between the oil fields and the fishing grounds:
The Olympic Commander, Normand Aurora, Skandi Caledonia, Helliar.
On the high decks, men in yellow oilskins lean over the ship rail and watch the women run.
For a moment I stand between them, the earnest women, the wistful men, feeling for both but belonging with neither.
The sun is low in the sky, and there's an Arctic bite to the wind. I pull up my collar, and hurry into veins of the granite city.
