One of Brian Kelly's favorite activities is doing yard work with his father.

So when his dad, who is a Captain in the Air Force, left on a 6-month deployment, Brian was heartbroken.

That's why he ended up knocking on Dean Cravens's door.

Dean would often watch Brian and his father hang out in the yard together – so when he saw the little boy at his door looking for a yard work partner, he was more than happy to say yes.

Every day for the last six weeks, Brian has knocked on Dean's door, anticipating a day of fun in the garden. Even though Dean has a day job and a family of his own, he is always ready to spend time with Brian as a fill-in father figure.

While yard work may seem like a small gesture in light of what the troops do overseas, it is clearly no small gesture for the 5-year-old boy who just misses his father.
