There was this other instance when Chris was in the scouts. This could've been close to the same time during his day during elementary school, but he was pulled out. Possibly due to Chris' unbridled autism. That would've been a good time to learn some social skills. I guess bob told the girls "please be friends with my son Chris, but be careful, he's got autism." I assume there were programs back then, but at that time, Borb didn't trust any government system. Which turned out bad for Chris in the end.
