My room was so hot I couldn’t sleep last night. I opened both my windows, accidentally admitted a spider, closed the windows, slew the spider, and spent the rest of my night tossing my covers off my bed and then dragging them back on (until adrenaline ebb finally knocked me out, at which point I lucid-dreamed of tropical spiders until my alarm went off).
Finally this afternoon I took another look at the honest-to-God 19th-century radiator in my room. A girl with a smartphone should really have the technological know-how to turn off a radiator, but I ended up having to go to the front desk to ask the building manager.
