Once upon a time there was a boy who thought he was inept because he did not understand math well. This caused the boy to be lackadaisical while attending class.
One time during class the boy got an answer wrong on a test, which caused a kid to be ruthless and say something heinous towards the boy. The boy was mad, so he decided to go to the principle. The principle was skeptical about believing the boy because the boy explained the story inexplicably.
The boy was sad, so the principle said a facetious joke to make the boy laugh. The priciple told the boy that the kid was overzealous and naive to think he would get away with saying something mean. In the end, the kid got in trouble and no one said anything mean to the boy again.
