Personally , I did not like the ending.
But in all transparency and honesty, I have always loved wolves, since a child. I was hoping the boy and the wolf would be friends, with loyalty to one another.
I understand the moral of the story, which is, you can only control the outer world up to a point. Then you must train yourself to accept things that at present, you must allow it to be, knowing that it is the right thing to do. The story , in a subtle way, leaves the listener wondering if, in the future, once the wolf is comfortable with the boy’s scent, and knowing the boy committing to the wolf he’d be fed, I’m going to say the obvious. The wolf comes into town, and for a study diet of protein and grain, the wolf agrees to become the security for the small lonely town.
The new moral is, coexisting with the natural world is possible once you learn the ways of this world. Cheshire each moment, and you, like the wolf, will both be master of their domain.
