It's about to get real dusty in here. You've been warned.

The man in this video, Ryan Farrell, is celebrating his birthday with his family. His family just happens to include a woman, Misty Knight, who he has raised, but who is not his biological daughter.

As part of her birthday gift to him, she wrote him a very emotional letter, got him some gifts that seems to be inside jokes between the two of them (candy, a Batman vs. Superman onesie, etc.) But, it's what was hidden in the bottom of the box that will ultimately make you tear up.
