Example Input:  Person1:     Betty , would you please read this letter of application I've just written ? I'd like to have your opinion . 
 Person2:  I'd be glad to tell you what I think . 
 Person1:      Good ! I'm interested in your advice . 
 Person2:  If I were you , I would change the beginning . You should write about your education first because we like to judge a man by his abilities . 
 Person1:      Good idea , Betty . What would you think about the second part ? 
 Person2:  I think it's too short . You'd better say something about your work experience . 
 Person1:      You're right , I'll change it . How about the last part ? 
 Person2:  Very good . But you should talk about your family , too . 
 Person1:      I agree . I appreciate your helping me .
