When two friends are in the mood to chat, we have to go about it in a gentler and more dialectical way. By 'more dialectical,' I mean not only that we give real responses, but that we base our responses solely on what the interlocutor admits that he himself knows.
PlatoThe well-nurtured youth is one who would see most clearly whatever was amiss in ill-made works of man or ill-grown works of nature, and with a just distaste would blame and hate the ugly even from his earliest years and would give delighted praise to beauty, receiving it into his soul and being nourished by it, so that he became a man of gentle heart.
