Black or White
When I was at school, I used to argue a lot with my classmates and family members. Once there was a serious argument between my friend Bill and me. I have forgotten what the argument was about, but I have never forgotten the lesson I learned that day.
I was convinced that “I” was right and “he” was wrong – and he was just as convinced that “I” was wrong and “he” was right. The teacher decided to teach us a very important lesson.
She brought us up to the front of the class and placed Bill on one side of her desk and me on the other. In the middle of her desk was a large, round object. I could clearly see that it was black. She asked my friend what color the object was. “White,” he answered.
I couldn’t believe he said the object was white, when it was obviously black! Another argument started between my classmate and me, this time about the color of the object.
The teacher told me to go and stand where Bill was standing and told him to come and stand where I had been. We changed places, and now she asked me what the color of the object was. I had to answer, “White.”
It was an object with two differently colored sides, and from his viewpoint it was white. Only from my side it was black.
