 Person1:        Like what ?  
 Person2:Like renewing my passport , going to the travel agency to buy my plane ticket and figuring out what to do with my apartment while I'm gone .  
 Person1:        You are not going to give it up , are you ?  
 Person2:No way . I'll never find another apartment around here . But I don't like the idea of paying three months ' rent on an empty apartment , either .  
 Person1:        I don't blame you . Perhaps you could sublet it .

 Person2:That's exactly when I'll be away . It sounds ideal , as long as the landlord agrees .  
 Person1:        Tell you what , I'll be calling Jim late this week anyway , so I'll mention it to him then .
