For, as my friend Attalus used to say: “The remembrance of lost friends is pleasant in the same way that certain fruits have an agreeably acid taste, or as in extremely old wines it is their very bitterness that pleases us. Indeed, after a certain lapse of time, every thought that gave pain is quenched, and the pleasure comes to us unalloyed.”
