Don't over or under-dress. Don't believe all the evil you hear. Don't jeer at anybody's religious belief. Don't be rude to your inferiors in social position. Don't repeat gossip even if it does interest a crowd. Don't underrate anything because you don't possess it. Don't go untidy on the plea that everybody knows you. Don't contradict people even if you are sure you are right. Don't conclude that you have never had any opportunities in life. Don't believe that everybody else in the world is happier than you. Don't be inquisitive about the affairs of even your most intimate friend. Don't get in the habit of vulgarizing life by making light of the sentiment of it. Don't express a positive opinion unless you perfectly understand what you are talking about. Don't try to be anything else but a gentlewoman—and that means a woman who has consideration for the whole world, and whose life is governed by the Golden Rule, “Do unto others as you would be done by.”—Ladies' Home Journal.
