They become grown-ups whose only concerns are utilitarian. Trapped by the material, vulgar side of existence, victims of their own conceit, greed or intellectual laziness, grown-ups judge what a man says according to the way he is dressed (as in the case of the Turkish astronomer), gauge the beauty of a house by its value and think they know a young friend by how much money his father earns. Yet the child that once was is not dead: he is only buried, and an experience like that of the aviator (who is perhaps getting a little old ) meeting The Little Prince allows that child to come back to life.
