Mother's heartfelt reaction as soldier son surprises her at work after months away from home - Watch

Arizona: A Phoenix mother literally leapt for joy and into her son’s arms after her son gave her a surprise at her workplace.

The mother, who was not expecting her 26-year-old soldier son to see for another month, was left in a bundle of joy, after he purportedly showed up where she worked. 

Larry Sterns, who works as a janitor at Phoenix’s Central Station, when a security staff (who was also a part of the entire episode), asked her to help with a cleanup at a particular area of the plaza. 

As Sterns was towards the site, she noticed a soldier sitting on a ledge. It took her few seconds to realise that the young man clad in Army dress is her only son, Larry, who serves in the 101st Airborne Division of the Army at Fort Campbell in Kentucky. 

"I saw the Airborne patch and thought maybe I should say something, to thank him for his service," Denise Sterns told ABC News today. "Then I saw him starting to laugh, in his profile, and realized it was Larry." 

"I couldn’t even believe it," said Denise Sterns. 

Denise' father Terry Sterns, and brother Hugh Sterns coordinated the entire surprise with Larry and were off to the side capturing the emotional reunion on their camera. The video has been shared on Youtube and has gone viral.
