Multi-turn user requests:
user: Hey there, I noticed that all of my car doors seem to have locked themselves up, and with my schedule being pretty tight today, I'm in quite a pinch. I could really use your help to get those doors unlocked. It'd be fantastic if you could also switch on the headlights. It's getting a bit darker out here than expected, and visibility's not great!
