it’s hot as baals outside (30 C, 86 F). why yes, dear coworker, do keep your window and door open thus spreading the warmth through our entire air conditioned floor. I also tried to explain windows and blinds and hot air to my landlord yesterday because his sometimes-office is in our flat and it has a huge southwest facing window that he keeps open and unblinded the whole time whether his in it or not (the door he keeps locked). I don’t think it sank in. I think I’m gonna sleep at work tonight.
