These are the contexts of the quotes that have been tweeted from @sueannbowling from February 21 through February 27. All but the last are from The Fellowship of the Ring, by J.R.R. Tolkien.

Map showing the early part of the hobbits’ journey. This was a foldout in the original edition. The faint gray line follows Frodo.
“This is what I have really been longing for, for years.” Bilbo, as he leaves Bag End with the dwarves on his 111th birthday.
“I wish it need not have happened in my time.” Frodo in Bag End, after Gandalf has told him that Sauron has returned to Mordor.
“All we have to decide is what to do with the time that is given us.” Gandalf, speaking to Frodo in Bag End. This entire conversation was moved to Moria in the movie.
“Many that live deserve death. And some that die deserve life. Can you give it to them?” Gandalf, after Frodo has wondered why Bilbo did not kill Gollum when he had a chance. Again, in the book this conversation is in Bag End.
“Even the very wise cannot see all ends.” Continuing on from the last quote, and winding up, “My heart tells me that he has some part to play, for good or ill, before the end.”
“Now far ahead the Road has gone, and I must follow if I can.” Part of a poem recited by Frodo as he sets out with Sam and Pippin. Again, the movie differs from the book.
“What exactly are you doing?” Bowling, “Horse Power.” Roi has observed Timi working around a silkie’s rear end, and questioned him. (Timi is doing pregnancy checks.)
