''The Tell-Tale Heart'' by Edgar Allan Poe

      The main character of this story murders an old man, because of his eye, since it was like a vulture's eye. He says that he is not a crazy man and that his actions are completely rational. Then he describes the whole story and he tries to persuade us that he is a normal human and that he had to commit this crime. In my opinion, this man is absolutely mad, due to the fact that those who are really mad it is proved that they believe they are normal and that their actions are normal as well.
