Quote by River Song

"Spoilers!"

"I'm River Song. Check your records again."

"You can't change history. Well, that's what they always say. But they don't really mean it. You can change it, you just can't acknowledge that you've changed it."

"Hello, sweetie."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
