Who Are We Tonight?

"I'm in my bed." she replies at 10 p.m. from the sofa in the living room. "You're sitting on the sofa, here in the living room. You'll be more comfortable in your bed." I say.
"I guess I know where I'm most comfortable, don't I?" says she.
So we begin another shuffle, Elle and I, to get Nana into bed for the night. We haven't found our stride quite yet; have considered the possibility that there's none to be found. Elle's much better at it than I am most days.
Elle uses persuasion most of the time- which aggravates my Cochise-style personality. I want to herd all of Nana's peevish inclinations and corral them into reasonable behavior. Sometimes it works. Sometimes "herding cats" is an accurate description of it.
She's saying "ouch" a lot these last few days, but can't tell me what's hurting. There are two possibilities: one is that she's substituting ouch for another word, the other is that she may actually have an invisible source of pain. Given that her pain threshold is quite high (meaning that things that would seem like they'd be at least moderately painful don't elicit a response) I need to find out what is true.
Challenge for the day-- good thing it's the weekend because it will probably take more than one--
