Boorishness is coarse, offensive, inappropriate, or unseemly behavior. Gentility conveys a tone of decorum and propriety appropriate to each situation. It must never be a superficial cultivated display, or elitist, or condescending. It must demonstrate your genuine sense of equality with others. A prized character quality in any context, gentility expresses your civilized, worldly nature in a respectful, considerate way.
Your gentility can facilitate smooth human relations in our world.
