It takes some kind of person to throw your child away outside. Incredible. If I had done this to my child, I would be so overcome with remorse that I would not be trying to get away, I do not think I would care what happened to me. These two are a different breed. You can glean some insight into John's warped personality with that perennial smile of his, it is constant.
Personally the guy (JR) has always given me the creeps, perhaps that perennial and so often inappropriate smiling of his you mentioned, is a part of that. All I know is that there is something about him....something in his demeanor that has always raised my hackles. That being said, I've always wondered why, for those who believe the RDI, people find it more plausible that Patsy did it than John?
