No more sneaky reading

Sierra knows her books so well now that you can't really "improvise" anymore when reading to her. It obviously doesn't happen too often, or else she wouldn't get to know the books so well word for word, but sometimes if she is really tired and I know she needs to get down to sleep I would "abbreviate" what is on a given page--well, those days are apparently over. Take the following text, for example:

"Annabelle walked proudly down the school hallway, past the First Grade room, past the Second Grade room, and past her sister's Third Grade room, all the way to the cafeteria."

I innocently (??) summarized this page to read: "Annabelle walked proudly down the school hallway, all the way to the cafeteria"

After turning the page, here was the conversation that ensued:

Sierra (turning the page back): No! Read this page!
Me: I did read that one already.....
Sierra: No, you missed something!
Me: Oh, really? (Hmmm.....)
Sierra: Yes, it's First Grade, Second Grade and Third Grade!

By the way, this was a library book that we had checked out a couple of days before.
