The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration.
You'd say he did it to please the guards. Or maybe it's in order to do a good job with us. And I thought he was just to experience the feeling of a normal person again, even just for a short moment.
