Don't judge a book by it's cover

If one book looks difficult to read from seeing cover, it may be not so difficult to understand and it may be interesting. We should judge the contents after the reading. Not only books but also people is same. I meet many new people in April. I feel that I can't judge only looks of people, too. I can find many charming parts when I talk with. I want to talk more with my friend and teacher, then I will know some new and understand more about them!
