At a Baton Rouge barbecue joint on Thursday, Facebook founder Mark Zuckerberg provided some good advice to a local mother. 

Roxi Victorian, a ballet teacher, professional dancer and self-described "geek," introduced herself to Zuckerberg and his wife when she spotted him at Smokin' Aces BBQ on Government Street.

She told the social media CEO that her 9-year-old son is interested in programming.

"I never understand what he’s talking about," Victorian said. "I just encourage it in the most positive way possible."

Victorian told Zuckerberg that her son, Michael Dukes, talks about being a "white hat," a good guy hacker. Zuckerberg responded with a bit of advice.

"He told me to remember that programming was an art form and to continue to encourage my son to keep programming," Victorian said.

Zuckerberg founded Facebook, the world's largest social media community, while at Harvard University in 2004. This year, he has been traveling across the country with his wife, Priscilla Chan, to meet teachers and scientists in big cities and small towns.

"Priscilla and I are taking a road trip through the south this week as part of my challenge to visit every state in the U.S.," Zuckerberg wrote in a Facebook post about his journeys.

He posted, "After a tumultuous last year, my hope for this challenge is to get out and talk to more people about how they're living, working and thinking about the future."

Victorian said that Zuckerberg was friendly, but she didn't want to intrude on his lunch — a sampling of ribs, boudin and other Southern barbecue staples. 

"It looks like he was having a good Louisiana barbecue experience," she said.
