How should I care for my old parents, and what can it give me?
The butcher who first took care of his old parents
In the story of the butcher, the man first took care of his old parents and only then came back to the person waiting. When asked how he knew what he knew, the answer was to learn to take care of something with absolute involvement.
He said he needed to take care of them first, so he went in, looked after his old parents, and then came back and spoke.
