documents: #Person1#: How are you doing, Andrew? 
  #Person2#: Not well. I've been feeling pretty lonely lately. 
  #Person1#: But you have so many friends! How could you be lonely? 
  #Person2#: You know what they say'a friend to all is a friend to none'. I don't feel like I really know any of my friends. In fact, I should probably call them acquaintances, not friends. 
  #Person1#: What about me? I'm your friend. 
  #Person2#: I know you are, you are my girlfriend. I wish I had a guy friend to hang out with sometimes. 
  #Person1#: I know what you mean. I find it difficult to make new friends, too. It's not as easy as it was when we were young, is it? 
  #Person2#: Not at all. 
  #Person1#: I've made a lot of new friends since I started learning English. Maybe you could join a club or take a class to make some new friends. 
  #Person2#: That's a good idea. 
  #Person1#: What kind of qualities do you look for in a friend? 
  #Person2#: I'm not sure. I guess I'd like to meet some people who have a positive attitude and want to have a good time. 
  #Person1#: People who play ultimate Frisbee have a positive attitude; maybe you should join the ultimate Frisbee club. 
  #Person2#: That's a possibility. Thanks!
