Walking back through the woods alongside the river I spot a man on the path ahead of me. That is, I spot the top half of a man, a top half that is naked. Because of the windy path and the bushes I can't see if a) he has a dog, or b) he has trousers. My thinking is that if he has a dog then, even if he doesn't have trousers, he is less threatening than if he had neither.
Fortunately he has both.
