I think that's a fair question to ask someone who claims to live in a school. Someone said "Great, you don't live in my school." I replied, "I don't think anyone lives in a school." A third person said they did.
By itself, without the few lines above to provide context, it does look a bit odd. Still, I don't quite see how that would be against any rule. I don't think sleeping location is something that you could be found by. Answers would include a bed, hammock, cot, sleeping bag, futon, etc.
Although I do admit it is quite amusing to see how creepy this makes me look. This is slightly embarrassing.
