"He had one of those rare smiles with a quality of eternal
reassurance in it, that you may come across four or five
times in life. It faced, or seemed to face, the whole
external world for an instant and then concentrated on you
with an irresistible prejudice in your favor. It understood
you just as far as you wanted to be understood, believed in
you as you would like to believe in yourself."
The Great Gatsby - F. Scott Fitzgerald
