Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth. Macbeth is ranting about seeing the ghost at the banquet, and Lady Macbeth reminds him that he has guests.Macbeth. Blood hath been shed ere now, i’ the olden time,Ere human statute purg’d the gentle weal;Ay, and since too, murders have been perform’dToo terrible for the ear: the times have been,That, when the brains were out, the man would die,And there an end; but now they rise again,With twenty mortal murders on their crowns,And push us from our stools: this is more strangeThan such a murder is.Lady Macbeth. My worthy lord,Your noble friends do lack you.Macbeth. I do forget.[To Lords.] Do not muse at me, my most worthy friends;I have a strange infirmity, which is nothingTo those that know me. Come, love and health to all;Then, I’ll sit down.
