The dispute that goes on between Macbeth and his wife about the murder of Duncan is almost word for word a dispute which goes on at any suburban breakfast table about something else. It is merely a matter of changing ‘Infirm of purpose, give me the daggers’ into ‘Infirm of purpose, give me the postage stamps.’
