Input:  Person1:     Hi , Ann . I was wondering if you are free tomorrow night ?  
 Person2:  Well , George . I guess I am . Why do you ask ?  
 Person1:      I've just gotten a pair of pre-sale Star Wars movie tickets from a friend and was thinking of inviting you along for the opening premiere . Are you interested ?  
 Person2:  Yeah , definitely ! Thanks for inviting me .  
 Person1:      My pleasure .  
 Person2:  I really wanted to watch the Star Wars on the opening day , but the pre-sale tickets were sold out . How did you manage to get hold of them ?  
 Person1:      A friend of mine works at the corporate headquarters of Pepsi , which is a major sponsor of the movie . He was able to get the tickets for free , and then he sold two more for me for 50 dollars a piece .  
 Person2:  You paid 50 dollars for each ticket ? That's a huge premium over the regular price .  
 Person1:      Not really . Considering the fact that other people were willing to pay as much as 200 dollars each on the black market . Besides , I knew you were really looking forward to watching Star Wars on the opening day .  
 Person2:  Wow ! I am really honored you went through all this trouble just for my sake . I really appreciate that . So , what time are we going ?  
 Person1:      Well , let's see . The movie stars at 10 . We should be there at least 1 hour earlier , because there is a big line . I could pick you up at your house at 8 , if that's ok with you .  
 Person2:  8 pm , that's fine with me .  
 Person1:      Okay .  
 Person2:  So I'll see you tomorrow then at 8 .  
 Person1:      Yeah , that's great . I'll see you tomorrow night .  
 Person2:  Ok , George . Bye !  
 Person1:      Bye , Ann !
