Input:  Person1:     Is your lady beautiful ? Since I came here from the country , I've not seen her close . Tell me , is she beautiful ? 
 Person2:  Thomas , if I could write with the beauty in her eyes , I was born to look in them and know myself . 
 Person1:      And , her lips ? 
 Person2:  Her lips ? The early morning rose would wither on the branch if it could feel envy . 
 Person1:      And her voice like a lark's song ? 
 Person2:  Deeper , softer , none of your twittering larks . I would banish nightingales from her garden before they interrupted her song . 
 Person1:      Oh , she sings too ? 
 Person2:  Constantly . Without doubt , and plays the lute . She has a natural ear .
