21. 'I sit beside the fire and think of people long ago, and people who will see a different world that I shall never know.'
This person will sit and think and wait for what, as mentioned in the song?
From Quiz "Lord of the Rings": More Than Verses, Lore
Answer:
returning feet and voices at the door
Bilbo sang this song as Frodo was leaving Rivendell with his companions on the quest to destroy the 'One Ring' in Mount Doom. Bilbo gave Frodo his sword, Sting, and a coat of dwarf-mail which Bilbo took from his adventure in 'The Hobbit'. Bilbo also gave Frodo his good wishes and blessings along with these things and, to an extent, it protected Frodo in his perilous journey.
As mentioned in the song, Bilbo eagerly waited for Frodo's return. In fact, when Frodo asked how he could repay Bilbo for the items he gave, all Bilbo asked of Frodo was Frodo's safe return and collections of songs, tales and stories Bilbo could use in finishing his second book on Frodo's journey.
