What depressed Joe the most, and he never shied away from using the term 'depressed', was the fact that he knew he was right.
His honesty with himself brought him to tears, the knowledge that his sense of who he truly was weighed heavily on his mind, his ability to realistically see the world without bias or opinion struck him dully across the cheek.
Optimism was useless because the truth would always win the day. Pessimism pointless for the same reason.
Pulling the curtain back and seeing the pulleys and cables and trap doors in the light of day highlighted the mystery as false and the magic as fake.
He knew this.
He knew he was the sane one.
He knew more than he wanted to know.
