Lady Macbeth Act 3, Scene 1

Lady Macbeth is enjoying her power as queen. She is thinking of all the important things she must carry out so that everything seems normal. This is why she hinted to Macbeth that he needs to invite Banquo to the dinner. It would seem rude and odd if they had forgotten to do such a thing. She is still confident in her plans. Her main goal is to be convincing to all of those around her so that the plans don't fall through. She doesn't seem to think it is too difficult to put on an act for those around her.
