Input:  Person1:     Let me suggest this one . It's an excellent watch , it looks good , and it's only $ 100 . 
 Person2:  Hmm . That's not too bad . Does it have a stopwatch ? 
 Person1:      Uh , no . Analog watches don't come with stopwatches . You'll have to get a digital if you want a stopwatch . 
 Person2:  Oh . I see . Where are your digital watches ? 
 Person1:      Right here . 
 Person2:  I don't like this kind as much . Never mind the stopwatch then . I'll take that other one . Do you take checks ? 
 Person1:      Yes . Make it out to Time After Time . 
 Person2:  Here you are . 
 Person1:      Thank you .
