"There are a million moving parts to raising kids, and you can't always anticipate them all, especially when they are teenagers and their peers play such a huge role in their lives. If you offer independence, there is one kind of pitfall; if you shelter them too much, there is another. And sometimes you do everything right and something bad just happens. It's as simple, and as scary, as that."  -Anna Quindlen
