King Lear is another of Shakespeare's classic tragedies with many memorable lines on the price paid for vanity.  King Lear has three daughters, Goneril, Regan and the youngest the good Cordelia.  The King asks his daughters how much they love him and  thrives on excessive empty words of flattery from two of them and bristles with anger when plain speaking Cordelia does not wish to participate in such falsity.  The King banishes her and thereafter unfolds the tragedy of his own undoing.
