I'm thinking how people use the way they talk to influence others. By using inflections and intones, they influence, persuade, cover up, and make you believe what they are saying, even when it is opposite of what they are doing. We are taught this in speech class, but the real learning is through experience, from the people we meet and the people who have been in our lives.
It's a case of "actions speak louder than words" when you see a pattern in all their inflections and intones and nothing to show for it in the end, except usury and deception, and their own self-satisfaction of getting away with it.
There is no intellect in this: it's a low-level energy which only shows the persons true character and nothing more.
Oh, and it makes for great story-telling! What legends can be told ...
