Wherefore, in the first place, pains must be
taken that, if possible, no discord should arise
between friends, but in case it does, then our care
should be that the friendships appear to have burned
out rather than to have been stamped out. And you
must indeed be on your guard lest friendships be
changed into serious enmities, which are the source
of disputes, abuse, and invective. Yet even these,
if endurable, are to be borne, and such respect is
to be paid to the old-time friendship that he may
be in the wrong who committed the offence and not
he who suffered it.
In short: there is but one security and one provision against these ills and annoyances, and that is,
neither to enlist your love too quickly nor to fix
it on unworthy men.
