From this week’s What We Loved at World Hum: Last week, our second daughter came into the world, a tiny little thing. It’s an amazing time, but there’s also something about it that makes me feel like I’m already living in the past, as if today is just a photo that she will stare at while trying to imagine the world back then. Last week, I also watched Matt Harding’s dancing video. On the face of it, I thought it sounded like your typical self-promotional YouTube stunt. But by the time I got done watching it, I had tears running down my cheeks.

This might be because I’m feeling a little hormonal at the moment. But it could also be something else: With all the reasons to be pessimistic about the world our girl might grow up in, seeing Matt dancing his way across the planet reminded me of a simplicity, an optimism, a joy, a naïveté, a beauty and a laughter I too have found in the world. It’s a kind of love letter to humanity, and it makes me hopeful that when our girls finally walk out our door to see it for themselves, that they will fall in love with it, and that they will find themselves dancing, too.
