Example Input:  Person1:     why are you so upset today , Maria ? Cheer up !  
 Person2:  oh , Iris , it ’ s about the job with the PR company .  
 Person1:      it ’ s a great opportunity . You should be happy with the offer .  
 Person2:  but my mother won ’ t allow me to accept any part-time job . I ’ m afraid she will say no again .  
 Person1:      why ? It ’ s unfair . You can learn a lot from it .  
 Person2:  she says a part-time job is cursed blessing . It takes so much time and energy that I won ’ t be able to focus on my studys .  
 Person1:      that may be true . But I ’ m sure you ’ re able to find a balance between them . Why not try it ?  
 Person2:  I turned down quite a few offers before for her sake . But I ’ m a senior now , I don ’ t want to miss the chance this time .  
 Person1:      I agree with you but I think you really need to talk to your mother and tell her what's on your mind .  
 Person2:  I ’ ll try , but what if she insists ?  
 Person1:      just let her know that the experience will be both amazing and rewarding . And more importantly , you can manage both your study and the job .  
 Person2:  do you think it will work ?  
 Person1:      sure . Every cloud has its silver lining . Just try .  
 Person2:  ok , I ’ ll do that . Thank you , Iris .  
 Person1:      sure . Good luck , Maria !
