If charnel-houses and our graves must send
Those that we bury back, our monuments
Shall be the maws of kites." (Act III. Scene IV) * Macbeth first sees the ghost sitting in a chair and is shocked and frightened by the sight. He can't believe his eyes, but no one else can see the ghost.
I pray you, speak not; he grows worse and worse;
Question enrages him. At once, good-night:
Stand not upon the order of your going,
But go at once." (Act III, Scene IV) * At this point, Lady Macbeth gets very nervous about what her husband is saying in front of his court and she tells everyone to go home that the King is just not feeling well. He is having a kind of fit that will pass.
