Get a new roll of string. Unwind several feet of it. Now wind it back so it is absolutely identical to the start state. You can’t. With a gun at your head you probably couldn’t. So which smartass decided that hosepipe and extension cables would fare better? Which smartass didn’t see that both these things twist and take on a life of their own when wound back. That hosepipes kink and cables twist and snake around the handles? That it can take longer than the task they were used for to get the things back. I hate that smartass. I want to wind some cables and hosepipes together, hook them round his neck and ask him to unravel that. And now I’m off to Amazon to buy a proper extension cable or 2.
