During the course of your life, you have met a great many people. As well as those you encounter every day in person—your family, friends and your colleagues at school and work—you see dozens of people from all over the world in the newspapers and magazines. And on your TV screen, you watch the behavior of hundreds more.
Think for a moment about these individuals you recall in your memory. Try to call to mind facial expressions and conversations you have grown accustomed to since your childhood... the comments some have made about their lives, their concerns and worries and the ways they express them... the remarks that colleagues repeat daily, and what others say amongst themselves about their families and financial problems.
