Suppose you were in town for a convention and did not want to return on the day you were supposed to. At home, a wife and children wait for you. You office expects you back to report on the conference and make them feel that they sent you for good reason. Maybe you have met a sexy and loose woman who makes you feel like you never have before. You feel alive. Perhaps you saw something negative in your industry. You went to an art show. Somehow, you've changed.
