Same here, noted how someone tried their leaves as it looked peculiar. Realised I was effectively tying grannies, changed the direction of my second loop; far more secure.

To me it's fascinating as it's something taught at a very early age, something used nearly every day, yet something a lot people seem to do "wrong" (inefficiently) by habit or ignorance.

But now my kids know and can suffer less unties, so that's good.

Similar thing for me, the "use a food packet as a bowl" trick (eg for crisps/potatoe chips).
