F. Scott Fitzgerald said this quote

He was changed as completely as Amory Blaine could ever be changed. Amory plus Beatrice plus two years in Minneapolis - these had been his ingredients when he entered St. Regis'. But the Minneapolis years were not a thick enough overlay to conceal the Amory plus Beatrice from the ferreting eyes of a boarding school, so St. Regis' had very painfully drilled Beatrice out of him and begun to lay down new and more conventional planking on the fundamental Amory. But both St. Regis' and Amory were unconscious of the fact that this fundamental Amory had not in himself changed. Those qualities for which he had suffered: his moodiness, his tendency to pose, his laziness, and his love of playing the fool, were now taken as a matter of course, recognized eccentricities in a star quarter-back, a clever actor, and the editor of the St. Regis' Tattler; it puzzled him to see impressionable small boys imitating the very vanities that had not long ago been contemptible weaknesses.
