My mum used to say when I was a small lad that if one complied with social conventions, no harm would result. This was just after she caught me 'writing' my name in the snow by peeing. However, that sort of thing was always reputed to have other associated angers - electrified fences for example. I was often tempted in the wilder parts of my hill-walking jaunts just to splash and dash on the sheep control fences. Maybe it was the story of this sort of thing?
