As if learning to speak a foreign tongue wasn't tough enough, there's also the body language to master.
That's where Sergio Solazzo, a tour guide in Italy, comes in.
He was recently filmed explaining to a group of American tourists how his fellow countrymen communicate using solely their hands. "There's an entire dictionary," he says, before revealing how to convey a host of phrases.
YouTube user Slo Bender posted the footage online on Friday.
"Sergio, the tour guide, is a great ambassador," Slo Bender wrote in the video's description, alongside a link to the website for tour company Nada's Italy. The clip (above) is now going viral, having garnered more than 120,000 views in 48 hours.
