“Helvidius Priscus saw this, too, and acted on the insight.
When Vespasian told him not to attend a meeting of the Senate, he replied, ‘You have the power to disqualify me as a senator, but as long as I am one, I’m obliged to attend meetings.’
‘All right, then, attend the meeting,’ says Vespasian, ‘but don’t say anything.’ ‘Don’t ask me for my opinion and I’ll keep quiet.’
‘But I’m bound to ask you.’ ‘And I’m bound to say what seems right.’
‘But if you speak, I’ll have you killed.’ ‘Did I ever tell you that I was immortal? You do your job and I’ll do mine. Yours is to put me to death and mine to die fearlessly. Yours is to send me into exile and mine to leave without grieving.’” (Discourses, 1.2.19)
