Is it just me or does everyone feel sad at the beginning of Lord of the Rings (book)?

[Tinuviel the Nightingale]

I think I can find a name for the emotion that Luinalatawen was talking about. For me, I feel a sense of foreboding, especially towards Sam, when he jumps for joy (no wait he cries) at coming with Frodo. I sort of think, You have no idea what you're getting yourself into boy.
