Northern Irish man John McAleenan has been living in the United States since 2012, and decided to surprise his mother this Christmas season by returning home unannounced. After picking John up at Dublin Airport, his brother took him home and set up a camera to capture the moment that Mom would find him in the living room. When John later uploaded the reaction video to Facebook, he said it was “probably one of the best things I’ve ever done.” Credit: Facebook/John McAleenan
