Emotions about books

I sometimes don't feel anything about books. Sometimes I do feel things about books. One example is when I read "Marley And Me", I laughed at almost everything, then at the end since Marley died, I cried a little. It is a real emotional book. I was very surprised. One book I felt really nothing for is not really a book, but it is stuff like newspapers. Sometimes I feel emotional, but most likely I don't really care. When somebody dies I really care. Some things are just boring to me.
