"To talk and laugh. To do each other kindnesses. To read pleasant books together; to pass from lightest joking to talk of deepest things, and back again. To differ without rancor, as a man might differ with himself... these, and such like things, proceeding from our hearts as we gave affection and received it back, and shown by face, by voice, by eyes, and by a thousand pleasing ways, kindled a flame which fused our very souls together, and, of many, made us one." - Augustine, on friendship, in the Confessions.
