How can life be worth living, to use the words of Ennius, which lacks that repose which is to be found in the mutual good-will of a friend? What can be more delightful than to have some one to whom you can say everything with the same absolute confidence as to yourself? Is not prosperity robbed of half its value if you have no one to share your joy? On the other hand, misfortunes would be hard to bear if there were not some one to feel them even more acutely than yourself.
