Input:  Person1:       I think if I ’ m going to find a job , I ’ ll look over the job board .  
 Person2:Well , there ’ s no doubt that lots of people have found employment in the help wanted section .  
 Person1:        Right , so I picked up a copy of the Sunday Globe this morning .  
 Person2:Did you get a copy of the Herald too ?  
 Person1:        No , why should I ? The Globe ’ s help wanted section is the best .  
 Person2:That ’ s true , but still the Herald lists some jobs the Globe doesn ’ t have .  
 Person1:        Not enough to worry about . Why do I waste the money buying two papers ?  
 Person2:It's only a couple of dollars more . For that much money you can afford to risk it .  
 Person1:        I guess you ’ re right . I'll get a Herald as soon as I finish looking over the Globe .  
 Person2:Good idea .
