Why do you think it's so difficult for other characters to convince Don Quixote that the stories he reads are not real? Use specific evidence from the text to support your answer.

The books of chivalry have left Don Quixote incapable of seeing "reality." When Don Quixote believes that the inn is a "castle" or a "windmill" is a "giant," he is not merely deluding himself. He has subverted his physical senses. This is why it is very difficult to convince him otherwise.
