Lady Macbeth acts graciously towards other characters in the play--all except Macbeth of course. Lady Macbeth initially treats Macbeth harshly because she sees him as a weak man who lacks not ambition, but the strength to follow that ambition. She often chides his sense of masculinity to persuade him to act. However, Lady Macbeth regards other characters with outward respect. For example, on the night that Duncan arrives at Inverness, Lady Macbeth graciously welcomes him into their home, and Duncan believes that he is well regarded. Lady Macbeth is obviously covering her and Macbeth's true intentions, and her outward actions mask her inner feelings.
