So I have to say that for me the term “run-on” sentence brings up a specific grammatical form, and while I have been looking for one of those in my reading, I have not seen one. I have, however, found this great sentence which is kind of long and may be more of what Care had in mind.
“She’d exchanged her hoop earrings for bright tube-shaped danglers the size of bass-fishing lures, and her red lipstick for orange; otherwise, with that head of black hair gelled into daggerish spikes and eye makeup so exotic that it probably glowed in the dark, it was the same old Ann.” (The Book of Old Houses, p. 190).
I love how this sentence – without you even knowing the character – tells you exactly what the narrator thinks of her.

I also learned a kind of vocab word – “down easter” – which I think refers to people from Eastport, ME, where this book is set, or from that region anyway.

Thanks, Care, for a chance to think about this.
