how are the man and the dog similar? how are they different?

Both man and dog are used to the outdoors. They both can handle cold although the dog has a genetical pre-disposition for it. The differences are more pronounced. The dog knows the man's folly. He knows this guy is an idiot for going ahead despite the cold. The man's pride and arrogance clouds his judgment. The dog has no illusions about itself. The dog knows from generations of instinct the dangers of such cold. The dog also seems to know this man's cruel heart. He runs away from the man when he tries to turn him (the dog) into a sleeping bag.
