Read that in middle school , agreed the end was sad, personally I think he did it because he cared(trying not to spoil the end, so vague talk).Ahh, the hobbit was a good read. Anyone else read "of mice and men"? It's a fantastic read about a mentally disabled man and another man who looks after him traveling around the country side looking for work and trying their best to stay out of trouble that the mentally retarded man gets them into by accident. The end is sad though, won't spoil it.
