Multi-turn user requests:
user: Would you be able to convert 20 liters of gasoline into gallons for me? Afterwards, starting the engine to check for smooth operation would be appreciated.
user: With the engine happily purring, I find myself pondering over the tire pressure now. Might you check that for me? And if you can, share the tire pressure status (with message content 'healthy' or 'not healthy', nothing else) with tag '#CarMaintenance' and mention '@VehicleGuru'? Healthy is deinfed as all tire pressure between 32 and 35, inclusive.
user: Wonderful! I'd really appreciate it if you could assist in retweeting that fantastic post about tire maintenance.
