Love is Blind

Macbeth and Lady Macbeth don't have much interaction in ACT I, only a letter and a short conversation. However, in this little time the audience can see that Macbeth perceives Lady Macbeth different than the audience does. To the audience she goes off on long soliloquies, pronouncing her evil plans and vicious motives. Macbeth does not hear these, he instead is greeted by his wife who speaks more calmly about the murder. So still evil, but more toned down than in her soliloquies. The audience perceives Lady Macbeth as evil, while Macbeth shows nervousness and doubt, she does not.
