Can’t Explain Why Her Head’s Full Of Hot Air

(I have just moved into a three-bedroom house with two other people. I am sitting on the couch in the living room when I notice [Roommate], whom I met in college, just going up and down the stairs. She can be a little eclectic at times, so I don’t pay it any mind. Our other roommate is my sister.)

Sister: “Hey, [Roommate], are you okay?”

Roommate: *obviously confused* “I think we need to call the landlord now.”

Sister: “What’s wrong?”

Roommate: “The AC doesn’t work; it’s hotter upstairs than down here.”

Me: “The air isn’t on.”

Sister: “Yeah, and all the windows upstairs are closed, and you know, heat rises.” *shrugs*

(I don’t remember the specific field, but [Roommate] has a degree in a science field.)

Roommate: “No, it doesn’t. What did your parents teach you? That’s so dumb that you believe that.”

(My sister tried to reason with her, I went back to my book, and she walked away confused by how “dumb” we are.)
