" What does one person give to another? He gives of himself, of the most precious he has, he gives of his life. This does not necessarily mean that he sacrifices his life for the other—but that he gives him of that which is alive in him; he gives him of his joy, of his interest, of his understanding, of his knowledge, of his humor, of his sadness—of all expressions and manifestations of that which is alive in him. In thus giving of his life, he enriches the other person, he enhances the other’s sense of aliveness by enhancing his own sense of aliveness. "

― Erich Fromm , The Art of Loving
