In a disjointed partially lost episode; John (@jfcatto) criticises the practice of behavior charts as they sound crazy. Then realises that he basically does the same thing. Pete (@mr_van_w) then questions whether students should be able to question the relevance of learning. The answer is "yes and teachers should have an answer".
