Input:  Person1:     ok , so what have you got in store for me tonight ?  
 Person2:  I'm really sorry , Ethan . I tried so hard , but I'm afraid I could't find a Dutch restaurant in town . The best I could do was a German one about 15 minutes from here .  
 Person1:      what ? I don't understand .  
 Person2:  I though you said you wanted to have Dutch food ?  
 Person1:      Oh ! Ha-ha ! That's not what I mean when I said ' go Dutch ' !  
 Person2:  Huh ? What were you talking about , then ?  
 Person1:      ' going Dutch ' means to split the bill , silly !  
 Person2:  oath ... that makes so much more sense ! Ha-ha . Well , great , I don't like German food anyway !
