Multi-turn user requests:
user: I've completed the maintenance on my car and ensured the doors are unlocked. Everything, especially the tires, seems in good condition. Would you kindly assist in securing the remaining doors and initiate the engine in START mode? I want everything primed before I set off.
user: Also, let's not forget to boast a little online. Could you post an update regarding my impeccable tire condition on Twitter like 'Tire pressure is perfect!'? Don't forget to use the hashtags and be sure to give my friend Mike a mention as well.
user: Let's use the hashtags #CarCare and #TireHealth. Btw, I think Mike's user handle is 'mike53'.
