The robot sat on the edge of the dock, a structure made somewhat untrustworthy by time and environment. Tremendous inconvenience, not to mention possible water damage, shimmered under its dangling feet. It was precisely this probability that allowed the robot the focus on isolating signal from noise.
I caught one of the robots in a moment of self-contemplation and had to take a few minutes to sketch out the scene as I remembered it. I never did ask the robot what it was doing, what it was thinking.
