Avi and Sara may look human and live in a human world, but they are not human. They are the newest models of androids to labor for humans. Throughout the day, they go through the physical and mental strain of human life, even though the people who take advantage of them do not realize that. At the end of the day, they seek solace and comfort from each other in their minds, away from the cruel world that they were created in, and show that they may be human, if not more human and compassionate than the humans that created them.
