When my DD was 13, I thought aliens had abducted her and put this evil bioch in her place. By 14, things were smoother. No real problems since then...I strongly advocate sending them away to college! when she came home, after having her first apt., she was a stickler for turning off lights, television, etc. That was a funny reverse. After college, we gave her a "promotion" from child to room-mate as that would require her to be respectful and clean up after herself but not allow her to whine "i'm hungry, when is dinner?" Now, she lives abroad and wow, do I miss her.
