Love it! As a kid, I always felt that school was one long undeserved jail sentence. (The irony of my being a teacher now is not lost on me.)
I once did a school visit / book signing (I’m an illustrator) at an elementary school in Long Island that had this unsettling look to its architecture. I commented on that (at an appropriate time, of course, not during the presentation) and asked if the building had originally been built for some other purpose. I was not surprised to hear that it had originally been a juvenile detention center.
