From Catulus I learned not to dismiss a friend's criticism, even when it seems unfair. Instead, try to restore the friendship. I learned to speak well of my teachers whenever I get the chance, like people say Domitius and Athenodotus did. And I learned to love my children with real affection.
Of Catulus, not to contemn any friend's expostulation, though unjust, but to strive to reduce him to his former disposition: freely and heartily to speak well of all my masters upon any occasion, as it is reported of Domitius, and Athenodotus: and to love my children with true affection.
