I wouldn’t really call this a kindness but I like to point out people who go above and beyond and are loved by everyone they encounter.
Such is the story of this B/B- list mostly television actress who concurrently had recurring/main roles on two of the biggest network hits (different networks/no superheroes) of the past decade. In each of them, she was only supposed to be a guest, but she was no nice and so genuine to everyone that the writers changed storylines just to get her more episodes to the point where she was practically main cast in both shows at one point.
Just an incredibly wonderful person.
