Having your dad come home from deployment early usually does the trick, though.
Jasmine Robinson filmed this clip of her children being surprised by their deployed dad's early return home. He'd been stationed in Germany after a tour in Afghanistan.
There are two especially heartwarming moments in the clip: The older girls' face at :25 when her dad enters offscreen, and her refusal, at 1:10, to stop hugging him.
Here's hoping everyone currently deployed gets this warm a welcome home.
