If she likes feel good stuff, have her check out Searching for Sugarman. It's a documentary, guaranteed to make her feel good. About a failed singer/songwriter who became famous in South Africa without knowing it, was long thought dead, but instead was living an itinerant life in Detroit, by all outward accounts a "failure" in the modern American sense but by any reasonable measure achieved huge measures of "success" as a human. Was re-discovered by South African musicologists who set out to find out how he dies. When they find out he's alive, they talk him into coming over and doing a series of concerts for his massive (and previously unknown to him) fan base. Concert series is hugely successful, and he gives away all the money he earns to other people who need it more than him, and goes back to living alone in his evidently rundown shack in slummy Detroit.
You couldn't write a stranger, cooler story.
He was playing concerts in Europe this summer and I missed him by 3-4 days on our vacation. I would SO love to pay to see him play.
Please let me know if your grandma watches this, and if so what she thinks.
