If two friends ask you to judge a dispute, don't accept, because you will lose one friend; on the other hand, if two strangers come with the same request, accept because you will gain one friend.
When you part from your friend, you grieve not; For that which you love most in him may be clearer in his absence, as the mountain to the climber is clearer from the plain.
Perfect friendship is the friendship of men who are good, and alike in excellence; for these wish well alike to each other qua good, and they are good in themselves.
