Steven Wright

I have friends of mine that are actors or singers, and they're the classic guys where, they're onstage, and they're like, 'Okay, the blonde in the third row, seat 24, bring her to my dressing room.' I've never, never taken advantage of that, I swear to God.

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.
