Q: So why would there be a boarding school that does not provide at least a window unit to their boarding students in this day and age?
All the things in the book that seem really improbable are just things from my boarding school that I assumed would read as plausible because they had happened.
So, yeah, my boarding school did not (at the time) have AC. Window units were only available if you got a letter from a doctor saying you had asthma.
We were all obsessed with developing asthma, of course. Having asthma seemed like winning the lottery to me.
