The challenge of manners is not so much to be nice to someone whose favor and/or person you covet (although more people need to be reminded of that necessity than one would suppose) as to be exposed to the bad manners of others without imitating them.
Judith MartinOne reason that the task of inventing manners is so difficult is that etiquette is folk custom, and people have emotional ties to the forms of their youth. That is why there is such hostility between generations in times of rapid change; their manners being different, each feels affronted by the other, taking even the most surface choices for challenges.
Judith MartinWhen people start hurling insults at you, you know their minds are closed and there's no point in debating. You disengage yourself as quickly as possible from the situation.
