10. Laelius. Well, then, my good friends, listen to some conversations about friendship which very frequently passed between Scipio and myself. I must begin by telling you, however, that he used to say that the most difficult thing in the world was for a friendship to remain unimpaired to the end of life. So many things might intervene: conflicting interests; differences of opinion in politics; frequent changes in character, owing sometimes to misfortunes, sometimes to advancing years. He used to illustrate these facts from the analogy of boyhood, since the warmest affections between boys are often laid aside with the boyish toga; and even if they did manage to keep them up to adolescence, they were sometimes broken by a rivalry in courtship, or for some other advantage to which their mutual claims were not compatible. Even if the friendship was prolonged beyond that time, yet it frequently received a rude shock should the two happen to be competitors for office. For while the most fatal blow to friendship in the majority of cases was the lust of gold, in the case of the best men it was a rivalry for office and reputation, by which it had often happened that the most violent enmity had arisen between the closest friends.
