Then, as you can see, and can't unsee, she discovered that she was not in fact all on her lonesome. There was a man huddled down in one of the back seats. And it's hard to say who's the more horrified in this situation: the singer, her audience, or the viewer who has to watch this unfold on vertical video.
To her credit, she doesn't stop singing when she realizes he's there. She just keeps narrating her experience until she's off the train, mortified but not defeated.
She leaves the man with a final melody: "You have a good day."
We could all learn a lot from Stevie.
