Input:  Person1:     Hey Mike . I forgot about registration . I'm a day late , so all the classes are mostly full . What do you think I should do ?  
 Person2:  You're screwed . You can't do anything about that . You have to hope that you get some classes that will be useful .  
 Person1:      Do you think going to the registration building will help at all ?  
 Person2:  No . They will tell you the same thing in a worse way .  
 Person1:      Did you register yet ?  
 Person2:  Of course . Registering for classes is not something you want to miss .  
 Person1:      What classes do you think are still open ?  
 Person2:  Well , I know psychology 101 is a big class , so there will always be seats in that class . You can also get into Sociology .  
 Person1:      That's helpful . Thanks . But what do you think about philosophy . I wanted to take that class this semester .  
 Person2:  I took that class last year . The professor is really cool , so if you go to his office , you can have him sign a card that will let you in even if the class is full .  
 Person1:      He does that ?  
 Person2:  I guess that's because so many people drop out of that class .  
 Person1:      That makes sense . I think I'll do that . Thanks for all the help .  
 Person2:  No problem , man .
