Input:  Person1:     just don't understand why we have to take the subway . Look at this place . It's modern enough . But it's far from lively . 
 Person2:  It's convenient . People in network go everywhere by subway if they don't drive . 
 Person1:      This isn't network , Frida . We are in San Francisco . 
 Person2:  What's the difference ? 
 Person1:      We haven't come here in business but for pleasure . We should go out exciting . What can you see in the subway ? Nothing ! 
 Person2:  What can you see from a tram or a double-decker ? 
 Person1:      I can see people who are walking on the sidewalk . I can see cars driving on the streets . I can see the sun shining and beautiful flowers dancing in the wind . I can even smell the scent of flowers and the freshness of the air . 
 Person2:  But they are not as convenient as the subway . 
 Person1:      You miss the point ! We are not in a hurry to go anywhere . 
 Person2:  Well , maybe you are right . We'll be more amused in a tram or a double-decker than on the subway . 
 Person1:      I'm so glad you can finally see things in my way . Can we leave this dull place now ? 
 Person2:  What about the tickets ? I've already bought them . 
 Person1:      Just throw them away !
