Input:  Person1:     Have you signed up to join the company ’ s Christmas party ?  
 Person2:  Sure , I have . Will you join ?  
 Person1:      I will . You know , as a newcomer , I think it might be a good opportunity to get to know people from the other departments of our company in a more relaxed atmosphere .  
 Person2:  You are right . Our company ’ s Christmas party has always been an amazing occasion for everybody to relax and get to know each other better . It is also a time to make new friends and do some networking .  
 Person1:      I hope that it is not a formal one when the boss is there .  
 Person2:  No , it will not be formal at all . It is a fun time . You will love the game show . Please dress casually . Usually there is an over abandon of drinks , so be careful with that .  
 Person1:      Don ’ t worry , I can handle that . And I know if the boss is there , even it is an informal evening , it does not make a good impression to get totally drunk in front of him .
