"You mean, if you allow the master to be uncivil, to treat you
any old way he likes, and to insult your dignity, then he may deem you
fit to hear his view of things?"
"Quite the contrary. You must defend your integrity, assuming
you have integrity to defend. But you must defend it nobly, not by
imitating his own low behavior. If you are gentle where he is rough,
if you are polite where he is uncouth, then he will recognize you as
potentially worthy. If he does not, then he is not a master, after all,
and you may feel free to kick his ass."
-- Tom Robbins, "Jitterbug Perfume"
