You know that dream where you’re somewhere familiar, maybe your childhood home, but there’s a door, one that was never there before, leading to some impossible magical place? Having children did that to my understanding of love. Suddenly, a huge new ballroom opened up off of the little apartment I’ve inhabited so long: a whole new wing of love, grand and soaring and utterly overwhelming. This song revels in that wonder, and the video serves up a heartfelt visual analogy: Put two simple mirrors together and you get a stunning, unbelievable infinity.
