Some people say they are big readers. That they're so into books it's not funny. However the only way to tell is if they 1) Suddenly gasp when something exiting happens in the book. 2) Start talking to the book because that's not how they want the book to go. 3) Hurl the book across the room when one of their favorite characters dies. 4) Burst out laughing when something funny happens. Copy & paste this if you are one of those - Way too true!
