Found this...

... lovely little note in a pile of papers. It's a few years old; Meg is finally clear it doesn't work this way, with divorce or otherwise, and her threats and provocations like this are generally met with a smile, and not any kind of acquiescence or anger. Of course, she doesn't see me smile; I think mocking and shaming kids is noxious, frankly. It's just that life isn't so simple. And every divorced parent knows it's a pendulum; you could be favored one moment, ill-favored the next, but hopefully, always, your kids are certain in every cell that both of you are steady, solid, loving parents.
