...the discussion in the car was about the genre of the movie Gravity.
We both liked it. Bobbi pronounced it the best science fiction movie she'd seen in a long time.
I disagreed, on the grounds that it's no more science fiction than The Hunt For Red October. She pointed out there wasn't any such thing as a silent "caterpillar drive" missile sub, either.
Still, it's easy to forget that there's a tiny village, population six, passing 250-some-odd miles overhead every hour and a half or so.
