A man went on a walk one day. He left his house and journeyed. We walked down streets he was familiar with. He knew the people who lived in many of the houses. And he didn’t recognize others. As he walked along, he thought to himself. He saw signs in people’s yards. The signs expressed the owners’ preferences. Some were political signs — this was common because an election was coming up. The man commented to himself about these signs. He smiled at the houses where the people had put out signs of the candidate he favored. But his anger started to rise with each sign he saw of the opposing candidate.
