When I was in Grade Seven, I got into a fight with a boy in my class. When we saw our teacher, I said "I was right and he was wrong" and he was sure "I was right and he was wrong". The teacher decided to teach us a very important lesson.
She brought us up to a desk, placed him on one side of the desk and me on the other. In the middle of the desk was a large, round ball. I could clearly see that it was black. She asked the boy what color the ball was. "White," he answered loudly.
I couldn't believe his words! We had a fight again, this time about the color of the ball.
The teacher told us to go to the different places. I stood where the boy was standing and the boy came to my place. And this time we found different colors. I had to say "It's white now."
It was a ball with two differently colored sides. One was black and the other was white. From the boy's viewpoint(视角) it was white. Only from my side it was black.
My teacher taught me a very important lesson that day: Sometimes we need to stand in the other people's shoes in order to truly understand their viewpoints.
