A stunned grandpa tried and failed to hide his emotions when his grandkids flew across the country to surprise him for the first time in three years. When Stephen Hoffman, from Scottsdale, Arizona, heard the doorbell and walked outside ahead of his 70th birthday, he was met with a pair of blankets lying on his doorstep. A confused Stephen then decided to pull the blankets back, revealing granddaughters Sienna and Sapphire, who jumped out from underneath to surprise their beloved grandpa. Initially Stephen tried to act cool, freezing in shock before heading in for a run-of-the-mill hug – but, after a few seconds of realization, he started welling up as the moment became too much for him.
