"Sue Bones did, constantly, about her own abusive husband. But Hermione always kept quiet about how bad things were for her at home, and she was having just as bad a time as Sue. Worse, probably, because Ronald had the favour of Tom Riddle to justify with his own domestic violence. I think Hermione was just trying to stay strong, put on a brave face, for all of us. She didn't want us to know she was suffering just as much as the rest of us were."
