A sweet story of how we should Love and being Third Culture

I've been reading The Monkey and the Fish by Dave Gibbons. This is a cool story he references in the book. Enjoy!

Not long ago, a story in the news enchanted people around the world. Every night, Julio Diaz, a thirty-one-year-old social worker, ended his hour-long subway commute to the Bronx one stop early so he could eat at his favorite diner. But one night, when Diaz stepped off the No. 6 train and into the deserted station, something unexpected happened. He was headed toward the stairs when a teenager suddenly apperead and whipped out a knife.
When the assailant demanded Julio's money, he calmly handed him his wallet. Nothing so unusual about that. But as the young robber turned away, Diaz called out to him.
"Hey, wait a minute," Diaz said. "You forgot something. If you're going to be robbing people for the rest of the night, you might as well take my coat to keep you warm."
The boy was dumbfounded. He looked at Diaz with a what-in-the-world look and asked, "Why are you doing this?"
Diaz told him, "If you're willing to risk your freedom for a few dollars, then I guess you must really need the money."
Diaz told the boy that he was on his way to get dinner and said that if the boy was hungry, he could join him. So they went to diner and plopped down in a booth together, and when several employees came by to greet Diaz one of the regular customers, he kindly introduced the boy to them.
Stunned by the evening's turn of events, the robber asked Diaz how it was that he knew everyone there and remarked on how he was nice to everyone, "Even the dishwasher."
Diaz asked him if he hadn't also been taught to be kind to everyone. The boy told him he had, but he didn't think people acted that way in the real world.
The conversation turned a bit more serious when Diaz asked him what he wanted out of life.
The boy didn't express much of an answer.
When the tab came, Diaz told the teen he was going to have to pay the bill, since he had taken his wallet, unless he wanted to give it back, in which case, Diaz said, he'd be happy to pay the whole thing, his treat.
According to Diaz, the teen "didn't even think about it" and handed over the wallet. Besides treating him to dinner, Diaz gve him twenty dollars, just something to help him out.
In return, Diaz asked for his knife, and the boy, who'd threatened Diaz with that same knife not long before, quickly surrendered it.
Afterwards, Diaz said that treating people right, regardless of how they treat you, is the simplest and most promising prescription he knows to bring people hope and to make the world a better place.
