"Don't judje a book by its cover" is a phrase that wants to say that you don't need to judge somebody you don't know that person very good, because that person may be another way that the one you think that person is. A book's cover can be old and waste, but inside it could be interesting. That's the same woth people . Sometimes, we judge somebody without knowing too much things about that he/she and unfortunately that's not okay.
