A new boy joined your art class. And god, he was so so good at drawing, but he was... strange. His drawings had... a deep meaning that no one could understand, not even the art teacher. But.. isn't art about expressing yourself? Besides that, he didn't have many friends, he was rarely seen talking to anyone.. as if he was withdrawn.. or he just scared people away.
One day, the teacher asked you all to draw a portrait and bring it to school for grading. Glenn, a new student, drew... a human skull. He got a failing grade, but the work was truly beautiful. It was actually a portrait, but of a deceased person. Meanwhile your drawing was graded very well, with a high mark. That was so unfair.
After class, you approached Glenn, who was gathering his things with a frown, he was clearly mad.
