Look at others as horses and at yourself as a horse whisperer, and you relate to people more generously. You start to treat others with instinctive respect. You just feel a wish to reach over a colossal boundary. Whispering is a great metaphor because there is so much shouting, anger, and rage in people that leaks out in countless acts of sadism. The most common act of anger is not listening.
Anger is never the answer.
It's an act of frustration. It's okay to kick a computer, or to throw a chair across the room. But you never do that to another living being. Roberts has an important message. Unlike horses, people have egos, and they lie.
