Input:  Person1:     Ok , so who are we going to invite to our dinner party ?  
 Person2:  Well , we have the Thompsons , the Greens , and the Anderson , about twelve people total .  
 Person1:      Don't forget my friend Andy from the office . He has nothing to do on Friday , so I invited him over .  
 Person2:  But that makes thirteen people ! We can't have thirteen people for dinner on Friday !  
 Person1:      Why can't we ?  
 Person2:  It's an old superstition . If we have thirteen people at the table , then it means bad luck . Can Andy bring a date ?  
 Person1:      I'm not sure . He just broke up with his girlfriend recently , and I don't think he's in the mood to start again so soon .  
 Person2:  But we can't have thirteen for dinner !  
 Person1:      I think you're making a mountain out of a molehill . It's only a superstition . It really doesn't mean anything .  
 Person2:  Absolutely not ! I refuse to have thirteen people for dinner on Friday !  
 Person1:      Ok , ok . I'll ask my sister to come . That way we'll have fourteen for dinner .  
 Person2:  That's better .
