Sarah mentions that her parents considered themselves Enlightened, but due to their lives being busy, they never had time to pursue their beliefs. Sarah says that by the time she was old enough, the idea of following any kind of organized religion seemed like an afterthought to her and was not important, saying that her mind was often at odds with her spiritual side. While Sarah was in high school, she and some of her friends were in a rock band. She makes sure to explain that she did not mean a school band, but a group called "Ironic Comet"
