All grown-ups were once children... but only few of them remember it. - Antoine de Saint-Exupéry, "Le Petit Prince." While I love de Saint-Exupéry generally, even in his time (especially?), he knew that not all children got to be children. Hell, I think even in his childhood, he never really got to be a child. The reason not many remember it is because for some, they really don't want to.
