Man is a social animal, as Aristotle once said. This want and need to belong and be accepted by others is what drives us to be civil toward others. In fact, there might be times when we want nothing but to see our intimidators get run over by a bus (yikes!) but we choose to endure the pressure and react in an amiable manner in order to merit niceties, as well. In order to achieve this kind of response from everyone we meet, we must strive to be likeable.
