Any lessons that you think that you've learned as a parent or any knowledge that you may have as a parent of non teenage children gets thrown out the window when they become teenagers. And so it's an extraordinarily challenging time for parents and my wife has been the one who's been more heavily involved with the children but I've never seen my wife more challenged in ways that I never would have expected. But on the other side there's a kind of opportunities to kind of indoctrinate them in really subtle ways that hopefully will carry through to adulthood.
