Maybe one day you'll be out in the middle of nowhere, and get dropped back a your aircraft, kilometres from the nearest civilisation, on a Sunday, and realise the aircraft's battery is nearly dead because you didn't notice the map light in the cockpit was accidentally left on when you tied her down two days ago. When that happens, I assure you that you will rue the fact that you did not learn how to swing the prop safely.
But I hope it never happens to you.
