If only that were actually true. Well, no, a lot of the time it does work, and I never say a word or I'm the one doing the explaining. The point of the example is that there's a fairly common pattern where people don't listen, don't become enlightened, and don't stop asking the same question because they've managed to get tunnel vision through staring at their non-working code for too long. At which point a short sharp verbal slap upside the head often serves to dislodge the cobwebs, at which point they start thinking again, read the explanation properly and become enlightened.
