  #Person2#: No, thank you. I had too much to drink yesterday evening. I had a bad hangover this morning. My head felt terrible. 
  #Person1#: Were you celebrating something? 
  #Person2#: Yes. It was a friend's birthday party. We drank all kinds of things-beer, wine and spirits. After midnight , we were even drinking cocktails! 
  #Person1#: It's a bad idea to drink a combination of alcoholic drinks. You should stick with one for the whole evening.

  #Person1#: I usually only drink beer and I rarely drink more than a few pints.

  #Person1#: Let me buy you a soft drink then. How about a coke? 
  #Person2#: Yeah. That's a good idea. I heard that coke was first used as a medicine. 
  #Person1#: Rally? . . . barman! . . . a large coke with ice and lemon, please... thanks. Here's the money. 
  #Person2#: Are you going to the wine tasting tomorrow? 
  #Person1#: Yes. I thought it might be interesting to learn a little about wine...
