I'll add a possibly pertinent detail: I shot this picture at my old school! I went to grade school in an old building that's since been torn down, but there was a separate three-room building that housed kindergarten, a music room and the cafeteria, plus two restrooms (one for boys, one for girls). I went to kindergarten in this building, had music classes here and had lunch here daily. The building is now used for things like a senior lunch program, and my extended paternal family rented it for a holiday get-together a few times. This restroom made us laugh. At one time, there was a dividing stall. No idea why somebody decided to take it out. I have another picture my myself and a couple of cousins posing in this room, laughing.
