The thing I disliked most in secondary school was reading a book in class and then dissecting the story. Every character, every plot twist, every comma was questioned until nothing was left to question. I disliked it because it was subjective. It was a one-side perspective from the teacher, that may not have been the perspective of the author.
Something I have since noticed when listening to people talk about their trade is that when they are asked for the deeper reasons behind their work, they often reply with bafflement. There were no deeper reasons when they designed, build or photographed something. It just felt right.
