When I was that age my parents let me swear as long as we weren't in public, because they knew the novelty would wear off if it wasn't totally restricted.
It worked, I got bored and tempered my language to the point that I rarely ever swear.
My older sister and I would say this not knowing what it meant. It was also from a VHS copy before the edited version. Fuck I'm getting old. Is it time for rice pudding and bingo yet?
