The Writers

Jeremy asked Tabitha, "How do we know we're not computer generated humans in a computer game played by real humans?"
They often bounced ideas off each other, as they were aspiring writers.
"What if we're computer generated humans in a game played by computer generated humans, played by real humans? And how about if it just goes on and on like those mirrors where you see yourself going on into infinity?" said Tabitha.
Of course, even given the possibility, it's a ludicrous idea. Except when you consider, the story you're reading is about two writers who, until now, only existed in the imagination of this writer.
