But the difference here is one guy is a celebrity and probably had a very very busy day to day schedule. Even then, he'd make time to meet up with Mr. Wang when they were in the same town.
I think the story is interesting because the two men came from very different backgrounds, yet discovered lots of common ground (minority skin color, achieved success despite modest upbringing, pride in their children). It's a story of a good friendship, one where you'd deliver a glowing eulogy at the other's funeral, if it ever came to that. I mean, I'm not sure how many folks I have outside of my own family that I'd have enough to say to deliver a eulogy. Maybe I need to make more friends?
I don’t think it’s reasonable to expect famous people — or anyone, for that matter — to stay in touch with literally anyone who wants to befriend them. Our attention and time is a finite resource, we have to make hard choices and commitments about who we give to and withdraw from. This is a story that wouldn’t happen without celebrity. Not just because Mr. Wang would not have otherwise recognized and talked to Barkley in their chance encounter, but seeing Barkley on TV continually helped keep the familiarity going, even if it was a mostly one-way street.
I bet Barkley gets many solicitations for his attention, and on the surface Wang doesn’t seem any different than other fans. But I think Wang showed his the genuineness of his friendship by showing up for the funeral service for Barkley’s mom. Anyone, fan or friend, could have seen the news and booked a flight to be there. That Wang dropped whatever work he was doing to be there for someone who he wasn’t close to (socially/geospatially) was a strong sign of how much he cared about Barkley.
It is also "traditional" celebrity interaction. Where the celebrity achieved status from professional skill building and achievement and largely unknowable through social media. So to know this person or have photos with them is a more scarce and unusual thing.
Wheras new celebrity status can be achieved through social media with no form of measurable achievement based on traditional skill building.
What's interesting about celebrity now is how many more people can be known and what skills can make you be known. Like, being beautiful and able to do finger dances on tiktok.
I'm not sure why, and it seems to me like I must be in a minority. I'm pretty sure every other upper-middle class person has one or two wealthy and/or famous friends. All wealthy and famous people can't only have friends that are wealthier or more famous than themselves, the math doesn't work out.
Instead, I see this story as an example of a very NPResque genre: upper middle-class parents often get cancer and die, surprisingly almost as often (proportionally) as the parents of people who do not work for NPR. But in the case of the children of the upper middle-class it probably hurts more because it's the first significant suffering they have ever experienced.
edit: I also assume it's pretty difficult to reject a story about a dead parent's "simple rules for living," interesting celebrity-filled early life with some artistic potential gone unfulfilled due to the choice to settle down and have children, or their immigrant story. They have a sentimental appeal for some readers/listeners, and your sad staffer won't be turning one in every week.
