Must lave our honours in these flattering streams,
And make our faces vizards to our hearts,
Disguising what they are.
– William Shakespeare
Macbeth, Act 3, Scene 2. Macbeth uses metaphors to suggest that he and and his wife wash their reputations in flattering of Banquo at supper and hide their emotions with vizards, or masks, to disguise what they truly are. Macbeth is expecting guests and doesn’t want them to suspect that he has despatched murderers to kill Banquo and Fleance.
