I was once positioning home in the bat suit minding my own business in 19C, when suddenly a pax in 19D grabbed my arm and said "I am so scared!!" just immediately after rotate.
Poor lad. He was from Peru and studying in Oxford but was travelling for some reason. I can't remember where.
He'd just survived his first round of medical studies exams and was just a bit overwhelmed with it all.
I chatted with him, reassuring him and just sat with him until he was ok.
