We can never replace a friend. When a man is fortunate enough to have several, he finds they are all different. No one has a double in friendship.
Friedrich SchillerAs freely as the firmament embraces the world, so mercy must encircle friend and foe. The sun poursforth impartially his beams through all the regions of infinity; heaven bestows the dew equally on every thirsty plant. Whatever is good and comes from on high is universal and without reserve: but in the heart's recesses darkness dwells.
Friedrich Schiller
