Today it’s 5 degrees outside and someone just got on my uncrowded train carriage and threw open several windows and it’s now freezing. Yesterday someone got on who looked like they had run or cycled to the station (sweaty) and politely asked if I would mind if she opened the window (a window that would blow directly in my face). She gave me daggers when I said I’d rather she didn’t. Less annoyed by the polite person of course but she did make me feel I was BU. If it was crowded or hot I’d understand it, but it’s 5 degrees! I’m wearing a coat, scarf and gloves as it is! AIBU?
