We recently moved around some rooms with the net effect of now having our downstairs guest room (on the kids level of the house, or as Dash calls it "Kid World") now having a bed and a couch in it and, crucially, no longer serving as my home office. The kids couldn't resist the temptation to move into the clean, spare space, and after a day or so of fort building, sleeping, and playing in there, Ella told me that it looked like a teenager's room. I have no idea where her notion of teenager rooms comes from and I suspect it gets a lot worse than this. But for now, we have our own version of a teenager's room in Kid World.
