You can fool some people, but you can't fool Mom. 

Famous film clip from 1934: "You can fool some of the people, some of the time.... but you can't fool mom". This was a common portrayal. No B.F.D. and, it shouldn't surprise anyone to see such attitudes being displayed, during this era. It once again debunks the myth of "female oppression" . IMPORTANT NOTICE to Cinematographe.
