It was true of course, what my dad had said: I did worship my grandfather. There were things about him that I needed to be true, and his being an adulterer was not one of them. When I was a kid, Grandpa Portman's fantastic stories meant it was possible to live a magical life. Even after I stopped believing them, there was still something magical about my grandfather. To have endured all the horrors he did, to have seen the worst of humanity and have your life made unrecognizable by it, to come out of all that the honorable and good and brave person I knew him to be—that was magical. So I couldn't believe he was a liar and a cheater and a bad father. Because if Grandpa Portman wasn't honorable and good, I wasn't sure anyone could be.
