It's kind of funny how every once in a while you can catch something that one writer does that unique to them and and no one else. It's like a fingerprint. In addition to "on the other (hoof, paw, anything but hand)", we now have the awkward conversation starter...
From this story ---------------
"Nessarose," she said simply as she sat.
"Glinda," Glinda said, not wanting to be left out.
From Psalm of the Lark....
"Dick," said Batman.
"Bruce," said Nightwing.
"Yahtzee," I said to no one in particular.
I LOVE it!! I have actually used "Yahtzee" that way after reading Psalm. Too much fun.
Oh, one other thing now that I think about it - actually goes back to the previous chapter... Have Glinda and Elphba acknowledged that there may be some sexual/romantic attraction between them, or are they still building to that?
