Yes, I know I've already spent a fortune on replacing all my robot components with real flesh parts. But to truly be human, I need more.
I want: random back pains. Hormonal mood swings. Never-ending self-recrimination. To distrust anyone who tells me they love me or think I'm a good person. To not be able to sleep even when things seem to be going well. To think that everyone else must surely be happier, and I would be too, if only I had what they have. To constantly, impossibly, desire more.
Only then will I know my transformation is complete.
