Got it. My guess has long been that there’s some exaggeration in it, particularly at the extremes. But that it’s reasonably representative.
In general though I’m more of the view that BS (and HS) are more alike than not wrt this kind of thing (i.e. sex, drugs, rock n roll), and that parents who believe otherwise are mostly deluding themselves. I don’t say that to be insulting, it’s just reflective of my take on the world.
