Many thanks. I told him that I hoped that I had been worthy of his devotion, and he told me I had been. which made me cry.
As it happens, the Return of the King is playing on tv tonight, and it turns out to have exactly the right balance of despair, sadness, honor, and triumph for my mood. It keeps choking me up (which it did the first time I saw it), and seems to be the right tonic for my situation. And I've always thought that Sam was one of the best examples of a boy in literature.
