Read this line from the story: "they do get on the nerves horrible," henry sympathized. what does henry's comment show about his character? his concern for the sled dogs his constant complaining his need to comfort his friend his need to take care of himself

I am thinking it is his need to comfort his friend ... I was first going to say his concern for his sled dogs ... but his statement " they do get on the nerves horrible ", without seeing the rest of context, might be talking about the sled dogs getting on his nerves.
