Input:  Person1:     What do you think of the new television channel ? Aren't the programs awful ?  
 Person2:  I quite agree with you . They are terrible . They are complete waste of time , but my wife disagrees with me .  
 Person1:      Actually , what bothers me is the violence . There are far too many detective and police shows .  
 Person2:  I couldn't agree with you more . There aren't enough educational programs , and even the news shows are not well done .  
 Person1:      You are absolutely right . They are too brief . They don't tell you anything .
