“If So-and-so challenges me, I shall lay before you a careful account of what I have said and done; if that does not satisfy him, I shall reciprocate his dislike of me.”
Siquidem locutus aliter fuerit, dabo operam ut rationem factorum meorum dictorumque reddam; si perseveraverit, in vicem eum odero.
Tiberius (-42–37 BC) 2nd Emperor of Ancient Rome, member of the Julio-Claudian dynasty
From Suetonius, The Twelve Caesars, ch. 28
