People who “sponge” have all the time in the world to waste your productivity with excessive talking. “Sponges” have been around for millennia. Ralph Moody describes one in his autobiography, Little Britches. “Then she told me (Ralph) that smart men like her father never did have to work hard, because they knew the world owed them a living and there were easier ways to get it than doing hard work. Charles Moody, the hard working rancher responds to his son, “Don’t you ever talk to that girl again…There are only two kinds of men in this world: Honest men and dishonest men. There are black men and white men and yellow men and red men, but nothing counts except whether they’re honest men or dishonest men. Some men work almost entirely with their brains; some almost entirely with their hands, though most of us have to use both. Any man who says the world owes him a living is dishonest. The same God that made you and me made this earth. And He planned it so that it would yield every single thing that the people on it need. But He was careful to plan it so that it would only yield up its wealth in exchange for the labor of man. Any man who tries to share in that wealth without contributing the work of his brain or his hands is dishonest.” Dishonest men are tricky and skilled at saying one thing (they are persuasively confident), but in their heart they mean something exactly the opposite. They are two faced people who cannot be trusted and are not your friend.
