You're a better woman that I am. I would've skipped the hot meal and shower part, said "Welcome home Sweetheart" on the doorstep in front of the media.
When that door closed, I would've said, "Sit down, don't move, and you ain't gettin' Jack Squat will you stop the crap and tell me the truth."
No brownies, no internet, no hair dryers. Hardball all the way. Shoot, when my daughter was 14 and was getting extremely rebellious and disrespectful, I woke her up one day and informed her that she was now, for all intents and purposes, Amish. I removed every electrical items from her possession, put a timer on the hot water in her shower, took out all the lightbulbs from her room lights, and said, "When you respect me, I'll respect you. Till then, you get nothing but three meals and a cot."
It only last about three days, and it worked wonders. She survived, and now knows that frills in life are a privilege to be earned, not a right owed to her.
