“When people talk, they do a lot of role-playing, side-step, shilly-shally, and engage in other forms of vagueness and innuendo. We all do this, and we expect others to do it, yet at the same time we profess to long for plain speaking, for people to get to the point and say what they mean. Such hypocrisy is a human universal. Even in the bluntest societies, people don’t just blurt out what they mean but cloak their intentions in various forms of politeness, evasion, and euphemism.”  [Pinker, 2007: 374]
