Provide the theme summaries for the following conversation: 

#Person1#: Anita, I've been here only three days and you're leaving already. 
#Person2#: Just for a few weeks. I need this vacation. You'll be all right. You know the project we're working on, and you're a good scientist. Don't worry. I'll be back as soon as I spend or gamble all my money. 
#Person1#: Gambling? Where? 
#Person2#: Las Vegas. I find gambling relaxing. I don't take it seriously, the way some people do. Besides, I love the shows and the all-night atmosphere of the town. The casinos never close, you know. 
#Person1#: If you gamble all night, you'll run out of money in a few days. 
#Person2#: Good afternoon, Dr. Green. I just finished showing Robert the ropes around here. 
#Person3#: That's good. He'll be able to keep the project going in your absence. Where are you going on your vacation? 
#Person2#: I'm going to Nevada to relax. The desert is a good place to get away from the stress of work. 
#Person3#: Enjoy yourself. We'll see you when you get back.
