Was the question, "WTF do you think you're doing?"
TLDR: YES, I thought it was gonna be exactly that.
I was taking pictures the entire day out with the kids to document the trip and so I was trying to get train car as there were no people in there at the moment. Next thing I know, several people brush past me, so I put the camera down and wait for everyone to be seated and I go back to shooting. She looked interesting with her big glasses, so I snap that exactly frame as she's turning to ask, "Excuse me, sir?! Is this train going to the mall?" A part of me thought, oh god, she's gonna ask me what am I shooting and why, but I've had several confrontations and there's no way it's gonna be as bad as the previous (with one guy getting all up in my face), hahahah.
Anyway, I didn't know myself and explained that to her and she got off in search of the right train. I soon found out that it was not the train back home so I got my kids up and left to the opposite side, looked for her to let her know and my daughter said she saw her walking down the road -- presumably to the mall (it's maybe 5-10 mins walking).
