Diagramming Sentences

Laurel is unhappy with the grammar materials we are using in school. I have spent the past few days planning out curriculum for next year and she has made it clear she wants to change that aspect of our school. Last night as we came in from church I asked her what she wants to change and tried to get a feel for what she doesn't like about what we are doing. Her answer was in the form of a question: "Why do I need to know how to diagram a sentence? When in my life am I going to use that skill?" Sounded sort of familiar. No fear, I had an appropriate response. It is just funny to remember when I was on the other side of the school table.
