But while our parting was mutually acceptable and even expedient, still it was painful. And I would like to think it hurt both of us, for I certainly felt it: a wrenching inside, like some small but improbably necessary organ was no longer in there, that it was missing, torn or fallen out. And at the time I'd thought that was the end of it; what was missing was gone forever
