Has anyone else noticed that even though Frodo keeps his thoughts to himself, everyone else always seems to know just what it is he's thinking? First in "A Conspiracy Unmasked", and now here. I'm not sure what JRRT was trying to say about Frodo, but in my mind it tends to diminish Frodo just a bit.
I also don't see it as diminishing him. I don't think they read him because he's shallow or anything, they can read him because they know his heart is true. IMHO :-)
