Answer 2

   In the act 1.2 of Shakespere´s play "Julius Caesar" there is a talk between Brutus; a friend of the Caesar who strongly believes in a government guided by the votes of senators and opposed to the ascension of his friend as a dictator; and Cassius; a talented general that envy the way the people saw Caesar as a human-god.

   At the beggining of the talk Cassius asked Brutus why his behaviour have changed during the last days, he did not seem the same person Cassius knew. Brutus replied that he had conflicting thoughts and that afected his behaviour towards his friends but Cassius shouldn´t be troubled, he would not let his inner turmoil affects his friendship.

   Cassius apologized for having misunderstood Brutus´s feelings and made him another question, this time he asked if Brutus could see his own face. He asked this knowing the negative answer to offer himself to performed as a human mirror because Cassius consider that Brutus did not see himself as the rest of the people did and want him to feel the respect they feel for him. Cassius did that not because he was a good friend, he did that to start to convince Brutus that people support and respect him and to lead him against Caesar and his growing power among the Roman people.

  This talk in the act 1.2 starts what further in the story will be the death of Caesar by the hands of Brutus who fell in the conspiracy of his so called friends.
