I am the tinny voice behind the man. I am the ideal. I have been created to walk the path of immortality. I creak and I squeak but aside from minor maintenance, I am indestructible. But I cannot cry. If I should cry, my jaw will rust shut, silencing me forever. So, to alleviate this problem, they removed my heart. Without a heart, there can be no feelings. And when there are no feelings, it's pretty difficult to cry.
