Input:  Person1:     Did you watch the Oscars on Sunday night ?  
 Person2:  No , but I heard about that Angelina Jolie and Brad Pitt didn't attend .  
 Person1:      Yes , that was surprising . I heard that they got into a fight and then decided not to go .  
 Person2:  They must be the most famous celebrity couple in Hollywood .  
 Person1:      They're also one of the richest couples . They have so much money and they can buy almost anything they want .  
 Person2:  I also heard that Tom Cruise and Katie Holmes made an appearance at the Oscars .  
 Person1:      Did either one of them win an Oscar this year ?  
 Person2:  I think Tom might have been nominated for one of his films , but I don't think he won anything .  
 Person1:      Tom Cruise may be handsome , but I think he's a bit crazy , don't you ?  
 Person2:  Yes , his marriage to Katie is actually quite scandalous .  
 Person1:      I still think that they only got married to get more publicity for their movies and themselves .  
 Person2:  People in show biz can have such an easy life ; I don't know why they have to make it so complicated .  
 Person1:      I would never want to be a celebrity because the paparazzi would also be after you .  
 Person2:  That's true . I guess it would be difficult to have people taking pictures of you everywhere you go .  
 Person1:      Thank goodness we're not rich and famous !  
 Person2:  Being famous , I can do without , but I wouldn't mind being rich .
