"All the world is a stage."
Someone once asked,
"If the world is a stage, where does the audience sit?"
The Antagonist says,
"There is no audience, just a stage."
If you understand that, you understand how the world works.
The full Shakespeare quote is:
"All the world is a stage, and all the men and women merely players. They have their exits and entrances; each man in his time plays many parts."William Shakespeare
If you understand how the full quote was bastardised into the innocuous phrase,'The world is a stage", you have even further insight into the way the world works.
