He has to know how to respect others, to the best of his ability, and interact in a way that can ensure he will never be wanting for his basic needs.
He collapses into me. Like a melodramatic actor from a 1950s stage play, he will fall into my arms while weeping over being denied a loaf of bread he tried to steal from the kitchen.
