"Yes! Are you grading papers?"
The older woman sighs and looks at the piles around the armchair. "Unfortunately."
"We'll stop bothering you!"
Next stop: the "library."
It is not as big as Hogwarts' library.
It is still pretty damn big.
"Whoa." Karen goes and looks at the books to see what they could possibly be about.
There's even a corner with a few books about magic! Very few of those, though, bought very recently during visits to Diagon Alley. Willow's schoolbooks are there as well.
A large part of the books are secondhand. In fact, the only ones that aren't are those that look like secondhand versions would be rarer than new ones.
Sadde definitely explores some of the magical ones. Having enough money to just buy books, just like that, must be so great.
"...Your cook doesn't go in the library, does she? If she spots the magic books someone may in fact show up at your house and forcibly erase her memory."
"No, definitely not, food's not allowed in here and she has little to do other than that. And when the cleaning lady comes there's this." She shows a little rolling door hidden in the upper side of the shelf that she can use to lock the books away. "We have lots of very valuable books here, hiding books is standard precautions."
Karen reads most of the titles, but does not actually take anything off the shelf to read. Next?
Next next is Willow's room. It is very spacious and has a very large bed and a television and a PlayStation and a computer and lots of movies in VHS and DVD and figurines everywhere, mostly from SF&F stories. There are four differently coloured toy lightsabers hanging on her wall above her bed, and she points at those and reminds Karen of them.
And because she had planned for just such a conversation, she turns her TV on and there's already a Star Wars DVD there paused on a lightsaber duel scene.
TVs are fun! And because Willow is Willow, she removes her shoes, hops onto her bed, grabs one of the toy light sabers, and starts swinging it around in time with the duel.
Attaaaaack!
Their duel has both the accompanying sounds from the TV and Willow's own personal sound effects. "Zwwwom! Chk! Bzzzzt!"
There are several movies. All of Disney's movies released so far, all of Star Wars, old movies like Gone With The Wind, a bit less old movies like The Godfather...
Satisfied that this is pretty much a kind of swordfight, Karen goes and gets a lightsaber too and joins the battle.
Now, three-way duels are way harder than just one-versus-one.
