Jon watched on the TV screen as Ms. Greenwald began grading papers. Almost immediately she cut herself. It wasn't just any cut, though. It was deep and it hurt a lot.
She tried to sop up the blood with tissues and after about a minute, it stopped bleeding. She went back to grading papers and got cut again. This time her finger seemed to bleed more. And the blood was dripping onto the papers she was trying to grade. "Shit," she whispered to herself.
Jon watched her on the TV screen, smiling. "That'll show her."
He looked down at the stone in his hand and wondered who else he could teach a lesson to.
