Just imagine the existence of a man - let us call him A - who has left youth far behind, and of a woman whom we may call B, who is young and happy and has seen nothing as yet of life or of the world. Family circumstances of various kinds brought them together, and he grew to love her as a daughter, and had no fear that his love would change its nature. But he forgot that B was so young, that life was still a May-game to her and that it was easy to fall in love with her in a different way, and that this would amuse her. He made a mistake and was suddenly aware of another feeling, as heavy as remorse, making its way into his heart, and he was afraid. He was afraid that their old friendly relations would be destroyed, and he made up his mind to go away before that happened.
~ Leo Tolstoy
