Thinking she has some inkling of what’s going on with Nana?
Or at least senses that the Mrs. is upset about something.
I wonder.
I can’t imagine that’s it. I mean she hasn’t seen Nana more than 2 or 3 times since April of last year. But you could be right that she might sense that the Mrs. has been upset, thus staying in the Mrs.’ desk chair where she rarely is.
