All right folks, the moral of this story is this: a guy is a hermit, because he doesn't like people. In fact, he downright hates people. Which is why he's a hermit. Because he's a hermit, he doesn't have any friends. But then here's this injured cat. He brings it home, feeds it, and is happy for the first time in a long, long time. He has a friend. But he leaves his cave, and while he's gone, wolves come and kill the cat, keeping the hermit from ever being happy.
You can interpet the shadows of the wolves as whatever you like...but they're wolves =P
