My almost 18 year old DD was caught out on the streets when she was 16. She was sleeping at a friends house, and I (being a responsible mother) called the parents to make sure she was staying there and also called again before I went to bed to make sure everything was ok.
Apparently the girls (there were 3 of them) snuck out after the parents went to sleep.....and knowing my DD it wasn't the first time it happened, just the first time they got caught. I don't blame the other parents, they can't sit at the end of the kids beds all night. I think it's something that is either in the kid or it's not. I honestly don't think my 15 year old DD will do it, but I am also not silly enough to think it is impossible.
