This from his final paragraph speaks to me in so many ways and I wanted to share it out loud here:
I believe that children of all ages are capable of deep thinking. I believe that they can shock us with their wisdom and their insight and their knowledge. But I also believe that they are kids. And as kids, they don't think like adults. Not entirely, at least. So, when you ask a fourth grader to identify the key details in a job application or you ask a second grader (who still can't comprehend the size of the sea) to learn longitude and latitude, it's about as absurd as having an open bar in the cafeteria.
