I wouldn't pretend to say I didn't know families with some inner upheaval but that would be some growing up. They would've been the exception. I didn't go to Public School, Private so there's that to help explain the dynamic of my statement. The public school examples I met though various other social outlets.
Seventh Heaven is the last successful sitcom I can recall that fit into the mold of what Cosby is wanting to return to. That ended, what, early 00's?
