HOUSTON – Stephanie Wyatt always knew her son Stefun was far from average, even as a small child.

“He would start giving,” said Wyatt. “Asking if anyone needed help with anything.”

He was always willing to lend a hand, but never too keen on wasting money.

“I’ve been eating pizza, microwave pizza for all my life,” said Stefun Darts. “My friends will tell you I never did go out. They didn’t know, but this was the reason why.”

And that reason was recorded on cell phone video. Family members captured the moment of Stefun’s most unexpected gift: He gave his grandparents a $15,000 check to pay off the mortgage of their home.

“I couldn’t believe it,” said Marilyn Roberts, Stefun’s grandmother. “To have a grandson like that is a blessing.”

For more than two decades, the Roberts have been paying their mortgage on time every month and were on path to pay off their house all by themselves.

But that would have taken them another four years.

“He’s a very special kid and I just love having him in my life,” said Cecil Roberts, Stefun’s grandfather.

Stefun is a full-time college student and also holds down a full-time job while running two small non-profits.

In addition to paying off the mortgage, he also gave his grandparents a trip to the Bahamas.

“I don’t do this for accolades,” he said. “To see tears of joy, to experience that in a lifetime, it’s like how many people can say that?”
