The earbud as regalia: Mark Montgomery, economics

Lately I've been flustered by certain questions from friends and colleagues that I could easily have handled a year or two ago. Someone might ask, for example, "Have you read Thinking, Fast and Slow, by Daniel Kahneman?" The correct answer is not exactly "yes," but not exactly "no" either. The fact is that I have listened to the book on my new iPod, but for some reason I don't like saying that. That response seems uncomfortably close to, "No, I haven't read the book, but I saw the movie." What to do? I've discovered that the problem can be sidestepped by saying, "Wasn't that chapter on attention and effort really fascinating?"
