Input:  Person1:     How were things in the Tokyo branch when you were there ?  
 Person2:  Good ! They have expanded and are doing better than they were last quarter . It's nice to see some improvement for a change .  
 Person1:      Do you see the trend continuing over the next few months ?  
 Person2:  Yes , especially with so many of our executives going back and forth from here to Japan . The only problem is , they may have trouble when they go to open up business here .  
 Person1:      Why would you say that ?  
 Person2:  They aren't too familiar with doing business outside of Japan . There are a lot of cultural differences to account for .  
 Person1:      I'll say ! Sometimes they just do things really differently . But one thing I can say , they are really hospitable .  
 Person2:  Have you ever been to Japan ?  
 Person1:      Sure ! I just got back yesterday . I'm still suffering from jet lag .
