I feel what Pa and Ma instinctively think about me (I don’t say reasonably). There’s a similar reluctance about taking me into the house as there would be about having a large, shaggy dog in the house. He’ll come into the room with wet paws — and then, he’s so shaggy. He’ll get in everyone’s way. And he barks so loudly. In short — it’s a dirty animal. Very well — but the animal has a human history and, although it’s a dog, a human soul, and one with finer feelings at that, able to feel what people think about him, which an ordinary dog can’t do. And I, admitting that I am a sort of dog, accept them as they are.
