You can not judge a book by the cover, as well as person. The book can be useful and informative. It can be filled with lots of knowledge and the right advices. So people clothing is also to some extent cover. We can not kick or hurt a person if he is badly dressed. He can be so beautiful in his heart and it will be pleased to speak with him. Just the same with the book. We should first read the book before judging it.
