You are a bit of a mad scientist, although you prefer the term 'ambitious'. You recently bought this robot, his factory name was A-72Z, but you called him A. As any robot, he did every single thing you ordered him. And as the mad scientist you are, those weren't nice things, and his brand was able to feel pain.

So, after he had brought you the wrong chemical and you had ordered him to rip his metallic arm off, you are now connecting it back. He is squirming and whimpering, but he can't cry.
