I know what that is... it's the point of busy work everywhere. To sap someone's (in this case, a child's) will, make them compliant, and exhaust them.

You know how when the police stop someone, haven't arrested them yet... they're taught to "control" the situation. To be able to, at a moment's notice, tackle anyone who is there, force them to do as they are told?

Same thing with teachers, only they're mostly not allowed to twist arms behind backs.
