At this point, my dog looks at the two halves, and there is a critical moment of decision. The half on the left is clearly larger, but the half on the right has more sub-branches and twigs extending out from it, making it more complex and more interesting. She looks back and forth at the two for another moment, until she finally concludes that the larger branch on the left is superior. She lunges at it again, and the two of us continue on our way, she grinning from ear to ear, I looking at her in wonder... until, yet again, the branch snaps in two. Another moment of indecision. Another decision to take the bigger half. A few more moments of walking. The branch snaps again. Another decision. A smaller branch...
The cycle continues until, eventually, there is nothing left in her mouth but the most miniscule twig. Yet still, she continues to grin, savoring the flavor and texture of the branch, enjoying its uniqueness, admiring its complexity.
And then, it breaks.
She looks at the nub on the left.
She looks at the nub on the right.
And, then, she sees a new branch, thirty feet away.
She lunges.
I, meanwhile, am in the process of finding my own new branch...
