Never assume that the person you are dealing with is weaker or less important than you are. Some people are slow to take offense, which may make you misjudge the thickness of their skin, and fail to worry about insulting them. But should you offend their honor and their pride, they will overwhelm you with a violence that seems sudden and extreme given their slowness to anger. If you want to turn people down, it is best to do so politely and respectfully, even if you feel their request is impudent or their offer ridiculous.
LAW 46 Never Appear Too Perfect Appearing better than others is always dangerous, but most dangerous of all is to appear to have no faults or weaknesses. Envy creates silent enemies. It is smart to occasionally display defects, and admit to harmless vices, in order to deflect envy and appear more human and approachable. Only gods and the dead can seem perfect with impunity.
