A group of “great kids” delighted a family in the Chicago suburbs when they broke into song to mark the end of the holiday period, with their sweet gesture caught on a doorbell camera.Meaghan Hejna was out when the boys called by on January 6, hauling a Christmas tree with them for one last moment of seasonal cheer. The foursome discussed how much they loved Hejna’s decorations, before bursting into Jingle Bells, and sending new year’s wishes, when no one answered.Writing on Facebook, Hejna said, “How sweet is this?! We weren’t home, but these boys still put on a show for our cameras! [M]ade me smile.” Credit: Meaghan Hejna via Storyful
