Margaret Mitchell said this quote

What Melanie did was no more than all Southern girls were taught to do: to make those about them feel at ease and pleased with themselves. It was this happy feminine conspiracy which made Southern society so pleasant. Women knew that a land in which men were contented, uncontradicted, and safe in possession of unpunctured vanity was likely to be a very pleasant place for women to live. So from the cradle to the grave, women strove to make men pleased with themselves, and the satisfied men repaid lavishly with gallantry and adoration. In fact, men willingly gave the ladies everything in the world, except credit for having intelligence.Scarlett exercised the same charms as Melanie but with a studied artistry and consummate skill. The difference between the two girls lay in the fact that Melanie spoke kind and flattering words from a desire to make people happy, if only temporarily, and Scarlett never did it except to further her own aims.
