In this scene, Lady Macbeth is [[anxiously]] waiting for the return of Macbeth after the murder. She worries in case he may have been caught and says she would have killed Duncan herself had he not [[resembled]] her father. When Macbeth arrives, he is [[distressed]] and [[unstable]]. He belives his punishment will be that he is unable to say [[Amen]] again or [[sleep]] properly. Lady Macbeth dismisses his worries and becomes [[frustrated]] with his behaviour. Shakespeare uses [[hyperbole]] to emphasise how much turmoil Macbeth is feeling whilst Lady Macbeth assures him that a 'liitle [[water]] will clear' them of this [[deed]].
