The change was like the tipping point when you're doing a jigsaw puzzle, and the pieces start fitting in from the moment you pick them up. and the picture is becoming clearer. The piece had fallen into place, and for the first time in David's life the picture was clear.
Their throat dry, David started cycling through sentences on the phone. Alex was silent--they knew that this was something David was working out for themself. "David is an empathetic bigendered centaur."
"David is an empathetic female centaur."
And in an eyeblink David was slightly smaller, rounder, with longer hair on the human part and both human breasts and horse teats. David turned toward Alex. "Alex, my pronouns are she and her."
Her face was radiant with joy.
