King Lear example Why should a dog, a horse, a rat have life, And thou no breath at all? Thou'lt come no more, Never, never, never, //never, never//. Pray you, undo this button. Thank you, sir. //Do you see this? Look on her! Look, her lips.// //Look there, look there. [He dies]// Robert Frost example There was never a sound beside the wood but one, And that was my long scythe whispering to the ground. What was it it whispered? I knew not well myself; Perhaps it was something about the heat of the sun, Something, perhaps, about the lack of sound— (excerpt from //Mowing//)
 * Lear:** And my poor fool is hanged. No, no, no life?
