One which you could not experience in the first person, because of obvious reasons like the fact you are yourself! If you could control a life, a person... Would you want to? If you felt you could guide this person and make a better job of their life than they could would you? Would you like to control a whole life from sitting at your computer?
I would never want to control another life for any reason. I have a hard enough time managing my own.
Ya know, I already sorta do. But not by choice..of course. I'm dating a girl that makes sure I approve before she takes a piss. Well, its not that bad..but still pretty annoying.
