Go armed against Discourtesy,

Go armed against Discourtesy, and against perfidy, presumption, and all other kinds of folly. There is much of it in the world, and prudence lies in avoiding a meeting with it. Arm yourself each day before the mirror of attention with the weapons of defence. Thus you will beat down the attacks of folly. Be prepared for the occasion, and do not expose your reputationto vulgar contingencies. Armed with prudence, a man cannot be disarmed by impertinence. The road of human intercourse is difficult, for it is full of ruts which may jolt our credit. Best to take a byway, taking Ulysses as a model of shrewdness. Feigned misunderstanding is of great value in such matters. Aided by politeness it helps us over all, and is often the only way out of difficulties.
