If thou see him going off to drinking, or to parties where there is nothing but drunkenness, then also do the same; and again on the other hand intreat him, if he observe that thou hast any failing, to help thee and set thee right. For in this way, he will even of himself, bear reproof, when he sees both that thou needest reproofs as well, and that thou helpest him, not as one that had done everything right, nor as a teacher, but as a friend and a brother. Say to him, I have done thee a service, in reminding thee of things expedient: do thou also, whatever failing thou seest me have, hold me back, set me right. If thou see me irritable, if avaricious, restrain me, bind me by exhortation.
