Watch closely… a tiny prank… and the wrong person suffers. Class is calm, teacher at the board. Suddenly, a boy flicks a lighter near his friend. A student notices: “What are you doing?!” Tension rises. The teacher senses trouble, walks over, no questions… and slaps the curly-haired boy. Shock freezes the class. The prankster laughs—wrongly. One joke, one innocent punished.
