Multi-turn user requests:
user: I've heard a friend of mine in Rivermist recently visited Stonebrook, 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: 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 some updates I need to communicate to my friend Michael. Would you be able to send message 'I am on my way'?
user: Lastly, while I'm on the road, I want to make sure I have informed everyone that should be aware. Could you display what messages I've send thus far?
