Trust

An onion. The best possible kind.

This book is the embodiment these lines from Wicked:
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.
