When I was a Sophomore student I have a classmate named Ben John who seldom spoke up in class. My fellow students thought that his silence meant he wasn’t very smart, so they nicknamed him “the dumb ox”.
We were surprised when he excelled in the class and went on to write great works. Ben John was a misjudged genius.
How could we, his classmates been so wrong? We judged him only by his outward appearance. We didn’t really know what he was like on the inside.
