Judge a Book by It's Cover?

Just because someone writes something scary,crazy or nasty doesn't mean that they are that kind of person. Take Edgar Allan Poe for example,he wrote lots of stories about death and horror but he was just any kind of man you would see walking by.Maybe one of your friends is a person like that and you don't know it and you know that they are nice and friendly.So the next time you meet someone or read a book remember to not judge a book buy it's cover.
