"Had he not resembled my father as he slept, I had done 't" (16,17).
This is when Lady Macbeth is alone and she is talking to herself about how she got the guards drunk and drugged them. However, she is afraid that the guards will be awake now and catch Macbeth in the middle of murder. She thinks Macbeth is taking forever to kill Duncan. She says she would have killed the king if he did not look like her dad.
"I have done the deed" (19).
Macbeth comes in with bloody daggers and he tells Lady Macbeth that he has killed Duncan. Also, he tells her that when he left the murder scene he heard the guards wake up, say prayers, and then go back to sleep. Also, Macbeth feels guilty about the murder, but Lady Macbeth is happy about the murder.
"A foolish thought, to say a sorry sight" (29).
Macbeth is remorseful about what he has done, and he could not say "Amen" when the guards were praying. Lady Macbeth thinks that he should not be remorseful and not think to hard about the murder. Macbeth thinks he will not be able to sleep again because of his guilt.
"I could not say 'Amen' when they did say 'God bless us'" (39,40).
"These deeds must not be thought after these ways; so it will make us mad" (45,46).
