For families with sons and daughters in the military, it's always nice when they come home on leave. When it's unexpected, the tears usually flow.
On a video on YouTube, Matt, a sailor with the U.S. Navy, surprises his mother as she is opening a large Christmas card that was delivered by a friend. He slowly appears from behind, stands and smiles as she reads the card.
Watch the video, and have a tissue handy to wipe away the tears.
