SF Drabble #496: "Hide and Seek"
She pauses on the stairs, turns her head slightly, closes her eyes, reaches out with a part of her mind only the Mothers know exists. Her opponent is two floors down, trying to do the same and finding only frustration. It is a game, they say with a smile. It teaches focus, concentration. The Mothers teach them wiles, and then talk to them as if they had none.
She continues further up, finds a suitable place, clears her mind completely. Even a candle is bright in the darkness. Her opponent will stumble into her trap, and lose, and be punished.
