I'm not sure if this fit's the bill, but....
On a flight to BGI i had a pax in first who's last living relative had died so she'd sold her houses and estates, cashed in all her savings and bought a place out there, she never thought she'd fly again and she'd probably never leave the island, i spent more or less the whole 9 hours talking to her and when she got off she was so nice that for a brief second i was almost emotional.
Sometimes we are such a pivotal part in peoples lives that it really does remind me why when i get off that stinking flying caravan that in 3 days time i'll get back on it.
