Come on;
Gentle my lord, sleek o’er your rugged looks;
Be bright and jovial among your guests to-night.
– William Shakespeare
Macbeth, Act 3, Scene 2. Lady Macbeth encourages her husband to shake off his troubled look, and be bright and friendly with their supper guests that evening. Macbeth appears to be ill at ease, weighed down by the guilt of killing Duncan and also arranging the murder of Banquo and his son, something his wife does not yet know.
