Elphaba, where I'm from, we believe all sorts of things that aren't true. We call it - "history."

A man's called a traitor - or liberator.

A rich man's a thief - or philanthropist.

Is one a crusader - or ruthless invader?

It's all in which label is able to persist.

There are precious few at ease, with moral ambiguities. So we act as though they don't exist.
