(Strip Number 6763, Original Publication Date, 8 January 1989)
Panel 1: We start things off with Elizabeth sitting in an armchair reading a book.
Panel 2: Liz puts the book on the seat of the chair and walks off to get something.
Panel 3: The strip proper begins with Elly noticing the book when she's vacuuming.
Panel 4: We kick things off by having Elly ask Liz is the book she's holding is hers. Liz says that it is.
Panel 5: Elly starts things off by pointing out that Elizabeth had left any number of pages dog-eared (thereby somehow managing to make the book worthless).
Panel 6: When she tells Liz to use a book mark to save her place, you'd think Elly had caught her trying to eat the book.
Panel 7: John tells Elly to not worry about it. Good luck with that. Elly can and will worry about everything.
Panel 8: Given that most of Lynn's lectures about the superiority of books is all about how it feels to hold one, Elly's question about how she's not supposed to worry about Liz's damaging the books are at least consistent with what we know about Lynn.
Panel 9: We zoom out to see the the Pattersons have a huge collection of videocassettes so that John's point about how at least Liz is actually reading a book instead of watching a cassette tape is made even more obvious. This is ironic given that when Lizardbreath becomes a shitty teacher, her go-to lesson plan is making the lesser kids watch films on tape so she can lionize her pet disruptive asshole unopposed.
Summary: I expect that if Lynn explains things, the notes will be all about how great it feels to hold a book, any book in your hands and how glowing screens just don't feel right to hold. They sure won't be about how Elly freaks out about every little thing or about how she should set a better example or something crazy like that.
