“Farewell," they cried, "Wherever you fare till your eyries receive you at the journey's end!" That is the polite thing to say among eagles.

"May the wind under your wings bear you where the sun sails and the moon walks," answered Gandalf, who knew the correct reply.”
― J.R.R. Tolkien, The Annotated Hobbit: The Hobbit, or, There and back again

“When I am in the darkness, I want to think of it in the light, with you," he said, and straightened, and turned to walk toward the door. The parchment robes of the Silent Brothers moved around him as he moved, and Tessa watched him, paralyzed, every pulse of her heart beating out the words she could not say: Good-bye. Good-bye. Good-bye.”
― Cassandra Clare, Clockwork Princess

“I don't know how you say good-bye to whom and what you love. I don't know a painless way to do it, don't know the words to capture a heart so full and a longing so intense.”
― Laura Wiess, How It Ends

“I remember the first time I saw you,” Allie said.
“I thought you smelled me first.”
“Right,” said Allie. “The chocolate. But then I saw you as I sat up in the dead forest, thinking I knew you. At the time, I thought I must have seen you through the windshield when our cars crashed…. But that wasn’t it. I think, way back then, I was seeing you as you are now. Isn’t that funny?”
“Not as funny as the way I always complained, and the way you always bossed me around!”
They embraced and held each other for a long time.
“Don’t forget me,” Nick said. “No matter where your life goes, no matter how old you get. And if you ever get the feeling that someone is looking over your shoulder, but there’s nobody there, maybe it’ll be me.”
“I’ll write to you,” said Allie, and Nick laughed. “No really. I’ll write the letter then burn it, and if I care just enough it will cross into Everlost.”
“And,” added Nick, “it will show up as a dead letter at that the post office Milos made cross into San Antonio!”
Allie could have stood there saying good-bye forever, because it was more than Nick she was saying good-bye to. She was leaving behind four years of half-life in a world that was both stunningly beautiful, and hauntingly dark. And she was saying good-bye to Mikey. I’ll be waiting for you, he had said…. Well, if he was, maybe she wasn’t saying good-bye at all.
Nick hefted the backpack on his shoulder. “Shouldn’t you be heading off to Memphis?” he said. “You’d better hit the road…. Jack.” Then he chuckled by his own joke, and walked off.”
