My history teacher asked why I always bring my textbook to class but only ever read the chapter summaries.

Punchline

I told her I'm practicing efficient scholarship—why wade through twelve pages when two bullet points contain the entire quiz?

Plus, the textbook makes my backpack look impressively academic, even if I'm just here for the Sparknotes vibe.
