One might have expected this quarrel to be forgotten as easily as their previous quarrels. But for some reason this particular flare-up was not forgotten. If two men’s lives are in harmony, they can quarrel, be wildly unjust to one another and then forget it. But if there is some hidden discord, then any thoughtlessness, any careless word, can be a blade that severs their friendship.
Such a discord often lies so deep that it never reaches the surface, never becomes conscious. One violent, empty quarrel, one unkind word, appears then to be the fateful blow that destroys years of friendship.
