Conversation
As soon as Elphaba discovered Galinda did think, she started to ask her questions on a variety of topics, which Galinda found very tiresome.
"Which came first, Animal or animal?"
Galinda sighed, "Does it really matter? They're both here, end of story."
"Oh, but it does! If Animals came from animals, it can be said that Animals are beneath us, as animals are. But if Animals came first, who's to say how they compare to ourselves?"
"Since we can't know for sure one way or the other, why bother arguing over it? It all sounds like rubbish to me."
"Exactly."
