Luca Cesternino is a nine yeard old Taekwondo student. His instructors told him he would have to go up against an instructor, while blindfolded.
But while Luca was blindfolded, it wasn't an instructor who stepped onto the mat, but his dad who had been deployed in Afghanistan for nearly a year.
As Luca is throwing punches, the voice of his opponent starts to sound familiar. Then the opponent starts calling him by his nickname. Luca takes off the blindfold and sees that it is his Dad who came to surprise him.
The rest is Dad/Son magic
Staff Sergeant Rob Cesternino, thank you for serving! Luca, enjoy your Dad!
