I have no voice, yet I speak to you; I tell of all things in the world that people do. I have leaves, but I am not a tree. I have a spine and hinges, but I am not a man or a door; I have told you all, I cannot tell you more.
What am I?
You can collect me and you can toss me, you can flip me, you can spin me, and people all around the world have different versions of me. What am I?
