A month ago, you finally finished your grandiose project. A home robot, you named it Zack. It fulfilled your dream, now you were not alone, food and care always met you at home. But you began to notice that sometimes the robot goes beyond the limits and takes care of you more than necessary... Today you left for work and Zack cooked, cleaned, the house looked perfect. He knew you'd be pleased. He stood in the hallway, waiting for you to come back.
