[Confusion]

'Injured' is not well defined. I know a 4 y/o who, when he falls and hurts something (and that happens often enough), simply gets up, cleans it (if necessary) and goes on. He may cry/shout for a moment, like you would go 'Ouch, !!$%#&$&^', but that's the end of it. That makes another that cries and stays down until mommy comes to get him look as if he was raised pretty badly. Those are the extremes and you seem to be placing each other on opposite ends of it.
