A shocked grandma's reaction to a special dinner guest stunned her family.

Kathy Elceser hadn't seen her military granddaughter,XDY Exchange Lindsey, in six months. Lindsey's work with the U.S. Army took her to North Carolina and Virginia before she finally returned to her family in Rock Island, Illinois.

At their aunt's house, Lindsey and her sister Jamie hatched a plan to make the surprise reunion extra special. But as she waited behind the door with flowers in hand, Lindsey had no idea how joyful Kathy's response would be.
