When I get my own place I want have a spare room that people sleep in. That's a spare room that people sleep in, not just for people to sleep in, or for the sake of having a spare room.

I like the fact that my house doesn't have any spare rooms. It did, but they filled up, so you can't call them spare. I like the fact that many nights there are only 3 rooms in the house that don't have people sleeping in them, and none of them are carpeted, and they all have sinks.
