The bulky figure coming towards me on the path has a stick in one hand, a small bag in the other, but I can’t make out his face because the dappled light that filters through the trees in the wood is playing with his features. As with most people, my mind drifts when I go for long walks and I forget about my surroundings until something like the cackle of a crow or a breaking twig or the heavy tread of somebody approaching, snaps me out of my reverie and, for a nanosecond, I am in the grip of a timeless uncertainty. I think of bandits, pilgrims, squires and ploughmen but, by the time we are a few yards from each other, I see the pleasant face of what turns out to be a maths teacher on a weekend break. His rucksack contains a plastic bottle of water, which he finishes off in a few gulps, and his stick is one of those Nordic walking poles.
