Leffid had used these little yachts for this sort of thing before; if you fed a nicely jagged course into their computers they’d do most of the bumping and grinding for you while leaving just enough apparent gravity to brace oneself without leaving one feeling terribly heavy. Programming in the odd power-off interval gave moments of delicious free-fall, and drew the small craft further away from the great world, so that gradually the view beyond the viewing ports increased in majesty as more and more of the conical habitat was revealed, turning slowly and glittering in the light of the system’s sun. Altogether a wonderful way of having sex, really, providing one found a suitable and willing partner.

They’d met at the Homomdan Ambassador’s party to celebrate the start of the six-hundred and forty-fifth Festival of Tier. He’d resolved to have his neural lace removed for the month of the Festival, deciding that as this year’s theme was Primitivism he ought to give up some aspect of his amendments. The neural lace had been his choice because although there was no physical alteration and he looked just the same to everybody else, he’d reckoned he’d feel more different.

Which he did. It was oddly liberating to have to ask things or people for information and not know precisely what the time was and where he was located in the habitat. But it also meant that he was forced to rely on his own memory for things like people’s names. And how imperfect was the unassisted human memory (he’d forgotten)!
