This is Ben.  I had a dream last night that I'm supposed to book a flight.  Can you help?
Where did you dream of going?
Pittsburgh of all places.
Where are you departing from?
San Francisco and I wish my dream took me to Hawaii.
Haha, Ben.  On what day?
It was hazy in the dreamscape, but I think it was a weekend day.  How about Saturday?
Right, I found a Business flight with Virgin for 434 credits
 that takes 3 hours to get to Pittsburgh.
That will work; what's the weather like in Pittsburgh on Saturday?
It will be Partly Cloudy all day on Saturday in Pittsburgh, with temperatures of around 22 degrees celsius.
It was snowing in the dream, but that reality sounds better.  What about Sunday there?
It will be Sunny all day on Sunday in Pittsburgh, with temperatures of around 27 degrees celsius.
Sounds fine, but not as nice as my current locale.
Is there anything else that I can do for you?
What's the weather like in Honolulu on Monday?
Unfortunately there are no forecasts that match your search. Would you like to change any of your criteria?
No, just daydreaming now.  I need ti learn how to reverse engineer these dreams of mine.
The flight is available. Should I reserve it for you?
Yes, book the flight to tropical Pittsburgh .
Right, your flight is now reserved!
Great, thanks.
Is there anything else that I can do for you?
No,that's all
Thank you and goodbye.
Bye
