Etiquette is from the French, which means ticket. A ticket to enter the royal court meant one knew the rules of best behavior. What we know as courtesy derives from best behavior at the royal court. Modern etiquette is important because it helps us become our best selves, so that we may lead positive, successful, happy and gracious lives. Etiquette also helps us become considerate and generous. It encourages fairness and empathy.
Knowing the rules of society means knowing the right things to do and the right words to say. Etiquette is a confidence builder, and as we get more confident through “knowing the rules of courtesy,” we show others how important those rules are in everyday life.
