Tween refusal in the morning often reflects a collision between genuine biological unreadiness and accumulated social or academic stress. A tween who is an Owl, running a sleep deficit, and carrying unresolved social difficulty is going to struggle to get out the door in a way that looks like defiance but is really a system that has hit its limit. Understanding the layers matters before responding to any one of them.
