MACBETH: What do you make of the fact that Macduff refuses to come to me when I command him?
LADY MACBETH: Did you send for him, sir?
MACBETH: It is a rumor, but I will send for him.
In every lord's household, I have a servant paid to spy for me.
Early tomorrow I will go to the weird sisters. They will tell me more, for now I am determined to know the worst that lies ahead.
My own good is now my only concern. I have waded so far into this river of blood that even if I stopped now, returning to shore would be as hard as going forward. I have some schemes in mind, which I must carry out before I can think about them too carefully.
LADY MACBETH: You haven't slept.
MACBETH: Come, let's sleep. These strange self delusions show that I need hardening—we are still children when it comes to crime.
