There's a lot of commentary in this book about what is and it not "normal." It seems like everyone has this idea that normal is a husband, a wife, kids, jobs, etc. Nick judges the swingers. Sister Edgar judges Ismael for being gay. The Texas Highway Killer, when calling in to talk to SueAnn says, on page 218, "I saw the interview you did where you stated you'd like to keep your career, you know, ongoing while you hopefully raise a family and I feel like this is a thing whereby the superstation has the responsibility to keep the position open, okay, because an individual should not be penalized for lifestyle type choices." When I first read this I imagined that the Texas Highway Killer was gay, but of course we found out that he lives with his sick parents, with no wife. Which, I think is supposed to be in contrast to Nick (who has a wife) taking care of his mother. So, I was wondering, if the Texas Highway Killer's motive to say that everyone is at risk. It's a bunch of random kills, so we're all on equal footing? It made me think of the rockets in Gravity's Rainbow.
