Hugh and Fiona stood off to one side, their hands linked and foreheads touching, saying goodbye in their own quiet way. Finally, we'd all finished with Claire and were ready to go, but no one wanted to disturb them, so we stood watching as Fiona pulled away from Hugh, shook a few seeds from her nest of wild hair, and grew a rose bush heavy with red flowers right where they stood. Hugh's bees rushed to pollinate it, and while they were occupied– as if she'd done it just so they could have a moment to themselves– Fiona embraced him and whispered something in his ear, and Hugh nodded and whispered.
