It's funny what sort of tricks the memory can play on you. I was reading Lars Walker's book, Troll Valley (which I'll review later this week), and early on came across a throw-away line about a book called "Mama's Bank Account", later made into a movie called "I Remember Mama". He said that the book almost never mentioned church. My mind came to a full stop, while it processed this, because I thought that "I Remember Mama" was absolutely packed full of church references.
Fortunately, my mind started again after a couple of moments, and I remembered that I don't think I actually read "Mama's Bank Account," though I once saw portions of "I Remember Mama" on TV. The books that I was thinking of were called "Papa's Wife", and "Papa's Daughter", by . Those were entirely different books (for one thing, the family involved were Swedish, rather than Norwegian), though the theme's probably similar, from what I remember. It's probably been a good twenty years since I read those books, though. I probably should look them up to see if the library has them (I have looked them up at B & N, and they aren't available as an eBook).
I'd say it's a pain getting old, but I think my mind always tended to mix together things of a similar theme like that. Then again, it's my provenly faulty memory telling me so. ;-)
