A city was under siege by an enemy army. The residents gathered to discuss how to defend against the enemy.
A bricklayer stepped forward, advocating for bricks as the best material for defense. A carpenter then proposed that wood was the superior method. Finally, a cobbler stood up and said, "Gentlemen, I disagree. In my view, there is no better material for resistance than leather."
This story illustrates how people tend to view things from their own perspective, often believing that what they are most familiar with is the best.
