It's funny, I used to do a character that was just a baby - just an adult baby. I would get up onstage and complain about adult stuff, but as a baby. I was in a diaper, and I would require hugs from the audience and reassurance and stuff.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
