Here's much to do with hate, but more with love," Romeo says at the play's beginning, and the dynamics of extreme emotion define the tone of the play (1.1.180). Romeo and Juliet deals in extremes that overlap or transform into each other. The Friar's lone voice of moderation is drowned out by storms of passion and violence; the insults tossed back and forth between the Montagues and Capulets alternate with Romeo and Juliet's loving exchanges of vows.
