From fairyninjas.wordpress.com: "A pretty hot tale of a bored AI and his human. Liked the premise and the smidgen of world-building that made it work."
"I'm going to reboot the warning subsystems, Cyrus." He'd taken to telling the program things like that before he actually went through with them. It made it seem more humane, somehow - the fact they were keeping something basically indistinguishable from a human holed up in a tin can to run their air conditioning. Clever, nimble fingers flashing, he typed a few lines into the console. After a moment, the cacophony outside quieted down. One of the folks on shift down below whooped in gratitude. Blake leaned back. "It's time we had a little talk, Cyrus."
"Oh good, I just love our little talks," the AI responded. Flatly. Blake frowned. That wasn't supposed to happen, especially not more than once in a row.
