My son was 16 when he decided he had been 'kidnapped' and taken to Phoenix by 'a friend' (we lived in California at the time) ..
..he was gone for 3 days, no contact at all, a relative called to say he had seen him in Phx and wondered what was goin on.
Wife was worried sick, called the police, hospital .. by the 3rd day she was a wreck.
He shows up back at the house, tells me to my face he was 'kidnapped' ..
..I explained that he no longer lived here. His mom .. my best friend, did not deserve to be put through that 3 days over some dumb-ass kid, son or not. I was dead serious. I did not care if he slept in a dumpster.
Now he's 32, married, a truck driver, ..and ya .. around 21 or so he became someone worth knowing again.
As a parent ..you can 'raise' a kid, teach 'em right from wrong, that you MEAN it when you say STOP when they run up to a curb with traffic just beyond .. but when that kid gets the idea they can do whatever they want without considering any consequences .. yer done.
Just my 2 copper.
-GE (and my daughter was very progressive ..she told my wife and I there was no way she would ever raise a hand to her kids ..not gonna happen .. then she had twins. .. then another. -evil grin- ..ya . . you gotta teach em to react to commands, and saying 'stop' a thousand times just dont cut it when they are runnin towards traffic .. and such)
