Input:  Person1:     What ’ s the life expectancy in your country ?  
 Person2:  I ’ m not sure , but probably about 75 years . How about in your country ?  
 Person1:      About 70 , I think . This newspaper article talks about the problems of an aging population . It ’ s a problem that will soon affect most of the world .  
 Person2:  I heard that the government might need to increase the retirement age , because otherwise there will not be enough workers to support the young and the elderly .  
 Person1:      Perhaps we need to have more babies ! Tina gave birth to a baby boy yesterday .  
 Person2:  Did she ? That ’ s great . However , if we have too many children , that will have a bad effect on the enviroment .  
 Person1:      How ’ s your son these days ?  
 Person2:  Oh , he ’ s fine . Kids seem to grow up very quickly nowadays .  
 Person1:      He ’ ll be a teenager before you know it ! Teenagers are often rebellious ! When do you mine it is a good age to have a child ?  
 Person2:  I had mine when I was 24 . that ’ s a little young . I ’ d suggest you wait until you are in your late twenties . , or even in your early thirties if you have a good career .  
 Person1:      Yes , I think you ’ re right . I ’ m thinking about having a child , but not just yet .  
 Person2:  Is there a big generation gap between parents and their children in you country ?  
 Person1:      Yes , there is . Teenagers do not want to live traditional lives . They want to go out , have fun , and explore the world . They want to develop their own view of life . Parents usually try to discourage them , but they don ’ t often succeed .  
 Person2:  Parents usually give their children more freedom in my country . Sometimes they give them too much freedom .  
 Person1:      It ’ s almost impossible to get the right balance . If you are too strict , kids might ignore you . If you are too lenient , they might go wild .
