user: Can you tell me their phone number?

system: You can contact them at 20 8365 2121.

system: I found 10 houses that fit your search. There is a 4.3 rated house found at 1 Addington Street.

user: That sounds like a great home.

system: Do you want to reserve this house?

system: What is your departure city and the dates of travel?

user: I need one ticket that's leaving from Seattle, WA and will begin on the 1st.
