"Hurt people hurt people." -my therapist "Hurt people! Hurt people!" - the little guy in red who stands on my left shoulder sometimes
And maybe ... "Hurt people? Hurt people?!" - the little guy in white that stands on your right shoulder? Anyway, one of my favourite quotes: "I love deadlines. I love the whooshing sound they make as they go by." (Douglas Adams)
Sounds like what the "Science of Discworld" books (by Terry Pratchett, Ian Stewart and Jack Cohen) called "Lies-to-Children", aka teaching. But they clarify and emphasize that what teachers do isn't lies, not really. Teaching simplifies a subject into something that can be more easily grasped. On the one hand, because the subject is simplified, the 'whole truth' isn't told; some details are left out, etc. But on the other hand, it's impossible to teach the 'whole truth' about a subject, or we'd be here all day. So how much do you teach without it getting overwhelming and boring, and without teaching so little that kids don't learn anything? *shrug*
