Nerves are acting up.

Two boys stand in a school hallway near a window, one in a light blue shirt and black pants, the other in a dark graphic sweatshirt. The boy in the blue shirt repeatedly swings a piece of paper or thin object in a circular motion, then briefly holds it up to his face before continuing the motion, while the other boy watches and smiles. A third boy in a striped shirt and vest enters the frame from the right.
