I remember when I first heard about Flat Stanley, when my oldest was in second grade. We never had our own Flat Stanley but my child came home and talked about the book, had me read the book, showed me pictures of Flat Stanley adventures her teacher had shared with them. I wish I'd had the wherewithal back then to send a Flat Stanley on his own adventure. I love that you and your grown child are still having Flat Stanley adventures. I really enjoyed reading about it.
