I wish I could clone myself. I share all of my fandoms and I know I'm ruthlessly critical. A clone would have the objectivity I lack, I hope. Of course, there would also be the problem that my clone would share all of my vices. A clone would inherently agree with my character decisions and depictions. Yes, perhaps a clone would be insufficient.
Still, I wouldn't mind a clone for other reasons. She could tidy my room, do my homework. Mmm. Cloney goodness.
