So The Kid asks, "How did the bad people get to be in the world?" [He asks often about good guys and bad guys. This is something that Cormac McCarthy absolutely nails in The Road. Little boys are very into this.]
Theologian Dad, with a sense of diplomacy: "I don't know, son. I don't know."
The Kid: "Well I'm going to kick them."
Theologian Dad: "Good job, son, good job."
The Kid: "Did you know that Jesus was born in a stable because there weren't any doctors or nurses back then? Did you know that? I figured that out by myself. Nobody told me that. I figured that out. There weren't any hospitals back then either, that's why Jesus was born in a stable."
Theologian Dad: "Uhh, okay."
