Nina and Max break clay into pieces as they sit side by side. Nina places her pieces into a tray with six recesses, having filled one tray already. Max wants the clay piece she has placed in the tray. He lifts the tray away from Nina. She makes a motion to retrieve the tray, but Max shields it from her reach. Later, she finds an opportunity to place clay pieces into the empty recesses, even though Max still claims the tray. Max shouts, “No,” and Nina stops placing the pieces in the recess herself. Instead, she hands pieces to Max, who lays them on the tray, but without targeting one piece per recess. Nina looks at the teacher as if she is pleased. Max shifts his attention to the clay that Nina is using. Increasingly, the actions that he directs toward the clay are also applied to Nina. The teacher quietly says, “Nina, if you don’t like that, you can tell him to please stop.”
