Thirty or so five-year-olds bounced around the free fall gym like a barrage of demented ping pong balls when their creche mother, a plump pleasant downsider woman they called Mama Nilla, assisted by a couple of quaddie teenage girls, first let them out of their reading class. But then she clapped her hands, and put on some music, and they fell to and demonstrated a game, or a dance, Leo was not sure which, with many sidelong looks at him and much giggling. It involved creating a sort of duo-decahedron in mid-air, like a human pyramid only more complex, hand to hand to hand changing its formation in time to music.

Nice kids, but aren’t they a little—feminized?” He was getting in deeper and deeper; her smile had quirked to a frown. “I mean—they just seem ripe for exploitation by—by somebody. Was this whole social experiment your idea? It seems like a woman’s dream of a perfect society. Everybody’s so well behaved.” He was uncomfortably conscious of having expressed his thought badly, but surely she must see the validity…
