Multi-turn user requests:
user: I've heard a friend of mine recently visited a place, and she mentioned the journey felt quite extensive. I'm curious, do you happen to have an idea about the actual distance between the two places?
user: The places are Rivermist and Stonebrook.
user: Covering the distance from Rivermist to Stonebrook sure seems like a long trip. I'm a bit worried if my vehicle can endure the journey with the current fuel level. I'm not entirely sure how far my car can travel on the remaining fuel. What do you think?
user: Thanks a lot! Before I embark on this journey, it makes sense to ensure I won't be left stranded due to an empty tank. Just add to the tank fully.
user: Great, with my tank now full, let's embark on this journey. Once I'm set to go, I'd appreciate it if you could start the car for me.
user: By the way, as I travel, there are critical updates I need to communicate to my friend, who goes by the unique identifier BD732D1888B94DAA. Would you be able to send a message on my behalf promptly?
user: Lastly, while I'm on the road, I might have the need to review any messages that have popped into my inbox. Could you display what messages I've received thus far?
