When you were young, were you all goody-goody? Or did you mess around?
More people were good kids when they were young than many want to admit. We all like to thing that when no one was looking our way we were radical, pushy, that we danced with the moon.
The truth of that is probably never really known, and by the time you have your own kids, you suddenly want to say "well, I never spoke to MY mother like that!"
Well, did you? Did you shout at your father? Did you tidy your room?
