I was just chatting with my mate about exactly this. His boy is refusing to do as he's told, when he's told. It's getting him into trouble at school. We discussed the fact that he has to learn now, because when he gets to the age to go and work, if a boss has a choice between two people, one who does as they're told, when they're told, and one who does what they feel like, if they feel like, there's a clear choice.

People who can't follow simple instructions are an absolute menace.
