I think we were both a little nervous about working together in the beginning, too. Just because you love hanging out with someone doesn't necessarily mean you're going to enjoy working together. Plus, our writing styles are different, as well, so I had no idea how we were going to approach this project. But I think we were both pleasantly surprised at how organic the process turned out to be and how much fun it was.
