I guess Bob didn't notice those mail packages from Adam & Eve, or maybe Chris was 'clever' and told him they were sent to the wrong address. I don't know how someone would be that oblivious, even for the fact that Bob was in control of Chris' bank account for a short time. Maybe Bob knew and just did not want to know any further. If I was Bob and knew about it, I'd be worried my sped of a son might choke on some thing or destroy his rectum with the anal beads or dildo. Come to think of it, I don't think Bob ever had the inclination to teach Chris about sex. Maybe before Chris' date with Emily, but I can't say for sure since there's nothing recorded on the CWCki about it.
