Husband made Fio very angry by insisting on telling her in detail about the true story of an Irish girl who was tortured and killed as a "changeling" because she was too smart for her own good. When Fio realized where the story was going, she cut him off.
The girl had been a real person, for God's sake, not a fictional character, and Fio felt for her!
Of course, Husband struck back by saying that if Fio didn't want to hear the story, she should have told him so first off. So now Fio isn't saying a thing to him, but she sure is writing a lot. Anger fuels her, and she learned long ago--as a child, in fact--that one can write what one is not allowed to say.
