From today’s Business Spectator

I experienced a rather unforgettable shock literally and figuratively when I was just five years old. Prior to that time I had always made what I thought was a reasonable assumption: a fence is a fence.

But on a traumatic day in the 1970s I discovered three things: first, and perhaps most importantly, dont make suppositions about the behaviour of things based on (limited) empirical observation; second, all fences are not run-of-the-mill fences in particular, some fences are electrified; and third, electricity is transmitted through fluids. Suffice it to say that I would not voluntarily relieve myself on an electric fence any time thereafter.
