But that's not what happened here, unless Sarah was lying through her teeth when she talked to the media about it. Her story was that she certainly knew Bristol and Levi had been dating, and had been planning to get married even before the pregnancy came along. Since everybody else in Wasilla seems to have known that Levi was a druggie party animal and that his mother was a dealer, either Ma and Pa Palin knew and didn't care, or they had their heads in the sand. If I'd gotten involved with a guy like that while I was in high school, my parents would have escorted me to school eavery morning and been waiting there to pick me up immediately when classes let out, and kept me under close supervision 24/7. They would also have talked to the school officials and made sure I wasn't in any classes with the scummy boy, and if at all possible, would have gotten me out of the school and sent me elsewhere (as the Palins apparently did with their eldest son, who from all reports was pretty much the same sort of young man as Levi).
It doesn’t matter if you take them to school or pick them up. If kids want to see someone, they’re going to find a way to do it regardless of how much you stand over them. I know nothing of Levi’s drug use, but, what I do know from raising 4 kids is that the more you forbid them to see someone, the more they’ll want to see that person.
So, your argument blaming the parents if futile. Bristol knew better, but, like so many other young people, gave into the temptation.
