oesn't want anyone to see the fatal blow he will give, including himself.
             Lady Macbeth recieves Macbeth's letter and reads it to herself. She is happy with the news of his prophesied kingship. The letter is contains terms of endearment and shows a degree of affection between the two. Obviously they have a close relationship now as Macbeth tells her everything about what has happened to him. Lady Macbeth does not think about what his news means for her but immediately lists his weaknesses and faults to herself. She considers ways to help him do what he must, 'pour my spirits in thine ear', to get the crown. She knows he is ambitious but she worries that he does not have the courage to carry out the deeds he plans. Then, after she is told of the King's imminent arrival, she calls on evil spirits to 'unsex her' and help her with her muderous ideas. She requests the spirits to remove her feminine qualities and make her more man-like in her deeds, words and feelings. It has a very dark, unnatural theme as she does not want to be what nature made her, she wants to be more manly in her feelings so she won't feel remorse or guilt. When Macbeth enters, she calls to him, calling him 'Great Glamis, worthy Cawdor'. He replies, calling her his 'dearest love'. Again, the affection between them is shown. Once she finds out when Duncan is to arrive and leave she insinuates that Duncan won't make it to the next day alive. Lady Macbeth tells Macbeth that he is to 'look like th'innocent flower, but be the serpent under't'. He is to hide his true desires underneath a facade of harmlessness. She uses euphemisms instead of mentioning the actual act of murder, perhaps to not pressure Macbeth at this early stage and make him not want to go throught with her plan or because she cannot deal with the idea of commiting murder, or plotting to commit murder, herself. Macbeth declares that they will speak further and she says that he should leave the plan to her.
