 Person1:       Nurse , I am sure to die soon . They just don't tell me the truth , I know .  
 Person2:But I don't think so . No one has ever said a word that you are to die , only yourself . That means you are not willing to die , right ? Actually , you are recovering and what you imagine as your worry is slowing down the treatment . Many cases worse than yours turned out to be hopeful and successful . You must be confident . Your condition is much better physically , but a little bi difficult mentally . The most important thing for you now is cooperation with us .  
 Person1:        Is what you said really true ?  
 Person2:Of course . I am a nurse and a nurse tells the truth .  
 Person1:        Thank you .
