And Then Things Changed Subtlely and Almost Imperceptibly

So I was reading to Katie from If You Give a Mouse a Cookie. We've read this book a lot.

"If you give a mouse a cookie, he's going to ask for a glass of milk.
When you give him the milk, he'll probably ask you for a straw.
When he's finished, he'll ask for napalm."

"Napalm!" daisy_knotwise cried out. "What are you reading her?"

"Apocalypse Mouse," I replied.
