The Notorious B.I.G.

I'm basically different things to different people. If it's a guy, I'm-a probably have my guard up because it's a street rule that when men come around that I don't know, I just immediately throw shade on them. But I don't associate with fellas all that much; if it's a girl - a beautiful girl - I be nice.

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.
