"I hadn't thought about the balance in mood. You see that we did it in alphabetical order, so if there's any kind of shape, or any kind of flow, it's random. Gender...we didn't think much about it. It was sort of interesting to see that women often were choosing women and men often were choosing men. And sometimes they wouldn't and that was fun. I didn't know that I would be excited by that, until I saw it happen."
