If one needed another reminder how hard it is on kids when a parent is defending our freedom half-way across the world, here it is.

In the video above, Greggs' older son, 6-year-old Teagan is unexpectedly -- and adorably -- overcome by tears when he hears of his dad's return home from Afghanistan.

To all parents serving in the armed forces.

To moms and dads willing lay it all on the line for our country.

To ALL serving our nation bravely across the miles...THANK YOU!

Watch the full reunion above, and try not to cry yourself.
