I Believe Parenting Is The Hardest Job Anyone Could Ever Have

My daughter is 15, looks 25, and already has the kind of figure that turns heads everywhere she goes. I've tried so many times to get through to her about all the dangers and predators out there for a young girl like herself but all I get are rolling eyes, huffing and puffing and a general attitude of 'whatever'.
I have banged my head against the wall more times over her in the last 2 years than in the previous 13 years combined.
