We rejoice in the joys of our friends as much as we do our own, and we are equally grieved at their sorrows. Wherefore the wise people will feel toward their friends as they do toward themselves, and whatever labor they would encounter with a view to their own pleasure, they will encounter also for the sake of their friends.

— Marcus Tullius Cicero
