The next day, at the appointed time and place for the duel, the tea master followed this advice. The soldier, readying himself to strike, stared for a long time into the fully attentive but calm face of the tea master. Finally, the soldier lowered his sword, apologized for his arrogance, and left without a blow being struck. The tea master showed great courage. He looks calm and confident, but it's an illusion.
Simple illusions can defeat enemies.
If you look like you know what you are doing, people will not think otherwise. Where I work all of the supervisors park inside the gate while everyone else parks outside. It's a matter of confidence. But I guess people in Japan think differently than we do. Maybe they are more able to see bravery in others, and even step back to swallow their pride.
