Think of the last time you experienced an emotion. Love, hate, fear, anger, embarrassment; it doesn’t matter which. Where were you and what were you doing? What was it that excited, pleased, or upset you? Chances are there was at least one other person around (even if only in your otherwise private thoughts), and that something that they did or didn’t do (or something that was done or not done to them) was part of what made you emotional. Now think about what happened next. Perhaps someone else reacted to your emotion, tried to calm you down, or responded with antagonism. Later still, maybe you discussed your feelings with someone close to you. Maybe, in some ways, the experience affected other people almost as much as it affected you.
