Help! I feel like I'm being held hostage by my 11-year-old son. This morning he said he had a sore throat and refused to go to school. But he didn't have a fever, ate cookies (without permission) and screamed at me. I ended up screaming back as I was late for work and frazzled. There have been other times when he has refused to leave the house with me, and I've had to cancel my plans. I take away privileges, but it just keeps happening. What do I do when he refuses to leave?
