If you're a fellow book-worm, then you'll agree with me when I say that every person who loves to read book, loves to read books in his or her own way. They have different tastes, different reading patterns and extremely interesting idiosyncrasies. You know any of these guys?
These guys will finish a book in one go, no matter now thin or fat it is.
They get emotionally attached to the characters in their books. They probably cried when Dumbledore died.
