Input:  Person1:       I heard that Janet has got a new job . She ’ s working for the united investment group . I heard that they pay very well .  
 Person2:I heard that too . She must be making a pocket . Well , good for her .  
 Person1:        Now , she ’ ll be able to save up for that holiday in the united states .  
 Person2:Yes , she will . At the moment , the exchange rate is very favorable , so she should try to go as soon as possible , while it ’ s cheaper .  
 Person1:        You ’ re right . By the way , did you hear that Tom inherited some money recently ?  
 Person2:Really ? I thought his parents had died several years ago .  
 Person1:        They did . He inherited the money from an uncle . I hope he doesn ’ t lose a lot of it in taxed to the government .  
 Person2:Dying can be very expensive nowadays ! What ’ s he going to do with it ?  
 Person1:        He said that he would probably invest most of it . He ’ s got a well-paid job , so he doesn ’ t need the money to cover day-to day expenses . He just wants some extra money available for when he retires .  
 Person2:I had some good financial news yesterday too .  
 Person1:        Really ? Have you won a fortune in the lottery ?  
 Person2:No , but I got a pay rise of 5 % and a bonus for all the hard work I ’ Ve put in recently . I think it was very nice for my boss to show his appreciation in that way .  
 Person1:        It certainly was ! So , what are you going to do with your windfall ?
