I would have gone into wherever my sister was and ask her if she could turn the light off. Or, if I was at my Mom's. I would walk to her room and ask her to turn it off if I was worried about breaking something. I am not shy about going and asking stuff like that, not really planning anything at all, just going and asking without contemplating anything. If they get mad, they get mad. I can't sleep with the light on. My mom has a ceiling fan in her living room with three light bulbs and I never like having it on. Luckily, it's easy to turn off because I just walk over to the light switch and flick it off and that's that. No need to ask anyone anything unless someone is using it, then they tell me not to turn it off but there's so many lamps in her living room, it wouldn't matter anyway because she'd turn a lamp on instead of using the ceiling fan.
