So Oz finally became home; the imagined world became the actual world, as it does for us all, because the truth is that once we have left our childhood places and started out to make our own lives, armed only with what we have and are, we understand that the real secret of the ruby slippers is not that “there’s no place like home,” but rather that there is no longer such a place as home: except, of course, for the homes we make, or the homes that are made for us, in Oz, which is anywhere and everywhere, except the place from which we began.

Now, as I look at the movie again, I have become the fallible adult. Now I am a member of the tribe of imperfect parents who cannot listen to their children’s voices. I, who no longer have a father, have become a father instead, and now it is my fate to be unable to satisfy the longings of a child. This is the last and most terrible lesson of the film: that there is one final, unexpected rite of passage. In the end, ceasing to be children, we all become magicians without magic, exposed conjurers, with only our simply humanity to get us through.
