Wow, that resistance to the thematic chapters is pretty powerful. Today's displacement activities included a rather long and complex negotiation with a friend to set up a Sunday brunch, paying bills, checking into tango class options...
All of that after an insanely late start to the work day, and followed by time working on the "Science and Science Fiction" chapter. That chapter actually needed more work than I realized; what I'd done was not only relatively sketchy but pretty well left out an important chunk dealing with the conventions of SF as a genre.
So I've been noodling around with that, while getting up to walk around every 50 minutes--and now I have to fold up my tents and pack up for tonight's sojourn into the City for tonight's dance class (and I have already paid for another for tomorrow, just to make sure I go).
Which means, my dears, that this is all I have time for tonight. But despite all the displacement activities, I did get some work done, which is all to the good.
