Middle school annexed my bedroom

I was in my bedroom (this time, resembling the guest room upstairs in Haymarket, which used to be my bedroom, but I had the impression that the rest of the house more resembled a bigger version of the Cantilever house). I was recalling how the middle school used to use the house for school space, including making my bedroom part of the lunch space, and then eventually it was also a classroom. For some reason, it hadn't bothered me at all at the time, maybe because the room was always in good shape when I went to use it (and I guess I was in school too, though maybe not middle school, so I wasn't around when it was in use). It was my impression that they didn't really rearrange the room when they used it, so many people must have sat on the bed.
