From the video description:
My buddy and I were clearing a right of way for the electric lines and came across this fawn trapped in the fall path of the tree we were about to trim. He was tangled in some thorns and was pretty shaken up after we cut him loose, so we started rubbing his belly to calm him down.... which worked a little too well, as you can see.
He followed us around the job site like a lost puppy for about an hour until I noticed a doe watching us from the hillside. Assuming this was his mother, I carried him about halfway up the hill while she watched attentively. I sat him down, he ran straight to her, and they walked off together.
I recommend watching it in full-screen mode.
All together, now: Awwww!
