Marilyn Manson speech on blame.
I have this goofy little headcanon where Dean starts calling Cas “angel” as a term of endearment (but only when they’re alone), and Cas doesn’t quite get why Dean is calling him “angel” (because obviously he’s an angel). And so he starts calling Dean “human” right back, and Dean kind of likes it, because it’s just so Cas, but he blushes whenever Cas says it around other people, because Dean knows how it came about, even if everyone else is just confused.
