Sitting in my car at the peak of a tall bridge in the middle of a crazy rainstorm.
It's 3AM. I don't want to go home. Ever.
Suddenly car pulls over and guy gets out and knocks on the window to see if I need any help. I tell him the car was acting up (it wasn't) and it might start (it did). He offered to follow me home in case it died again.
If he hadn't followed me home I might have decided to jump that night.
He probably thought he helped a stranded motorist during a crazy storm.
I remember looking for the grocery carts with built in ashtray.
