Confusion: My own.

Opening opening the pages of a book I had recently bought, Everything Bad Is Good For You, I discovered a piece of paper (photo below) with the words "STOP WAR" and a peace sign written. Bam! Confusion. At first, I figured I had grabbed the piece of paper as a bookmark- then I realized that the book was brand new, the paper was in the middle of the book and well towards the spine, not just floating around, and that there weren't any pieces of paper lying around with anti-war slogans on them that I might've picked up.

So where did it come from? Part of the back of the paper (really just a few black lines or arrows) makes me think it came from the packaging/unpacking step. Other alternatives are an employee of the store or a random patron. Why that book? Did someone forget the paper, or did they actually mean to pass it along?
Or is there some sort of vast left-wing conspiracy among book manufacturers? Or perhaps some sort of vast right-wing conspiracy designed to portray book-readers as hippies. The possibilities are as endless as they are mind-boggling (and improbable!).

Fun confusion on a small scale is often the best kind.
