A general rule of etiquette is that one apologizes for the unfortunate occurrence, but the unthinkable is unmentionable.

Judith MartinShame is the proper reaction when one has purposefully violated the accepted behavior of society. Inflicting it is etiquette's response when its rules are disobeyed. The law has all kinds of nasty ways of retaliating when it is disregarded, but etiquette has only a sense of social shame to deter people from treating others in ways they know are wrong. So naturally Miss Manners wants to maintain the sense of shame. Some forms of discomfort are fully justified, and the person who feels shame ought to be dealing with removing its causes rather than seeking to relieve the symptoms.
Judith MartinEtiquette is about all of human social behavior. Behavior is regulated by law when etiquette breaks down or when the stakes are high - violations of life, limb, property and so on. Barring that, etiquette is a little social contract we make that we will restrain some of our more provocative impulses in return for living more or less harmoniously in a community.
