Tween defiance often looks like contempt, refusal, or loud declaration of unfairness. Underneath is almost always one of three things: a felt lack of autonomy, a felt lack of connection, or a task that feels beyond their current capacity. The defiance is a signal, not just a behavior. Engaging with the signal rather than the surface behavior changes what is possible.
