When I was in a primary school, I argued with a boy in my class. I forget what the argument was about but I will never forget the 1 I learned that day. I thought that I was right and he was wrong, 2 he thought that I was wrong and he was right. The teacher 3 to teach us a very important lesson. She brought us to the front of the class and asked him to stand on one side of her desk and me on 4 . In the middle of her desk was a large, round ball. I could 5 see that was black. She asked the boy what color the ball was. “White,” he answered. I couldn't 6 he said the ball was white, while it was obviously black! Another argument started 7 us. This time it was about the 8 of the ball. The teacher told us to change the places and then asked me what color the ball was. I answered, “White.” It was a ball with 9 differently colored sides, and from his side it was white. Only from my side it was black. Sometimes we need to 10 problems from the other person’s opinion in order to truly understand his or her opinion.
