Not as hugely generous as this story, but during his whole college professor career since the 70s, my father always took care that none of his students spent any major holidays alone and away from home, so we always ended up having 2 or 3 of them around for Christmas, the New Year, Easter...
They were from everywhere around the country and the world, and it was so very enriching for me and my siblings. I had a huge postage stamp collection from the ever increasing well wishing mail that arrived.
It's also kind of comforting to think that anywhere in the world you are not that far from someone that remembers you fondly.
