Chris and I share a bathroom that is sandwiched between our bedroom and the mudroom and has no windows. Obviously, for a bathroom, this is not a big deal at all. This evening, I entered this bathroom to find blankets and pillows all over the floor. So I asked Megan why there were so many blankets and pillows in there. "We were making beds," she said. Of course, I thought, beds...in the bathroom...why wouldn't they? "Um...Why were you making beds in the bathroom?" I asked. "Because we were using flashlights and we didn't want to waste the flashlight by making them in the light."
Makes perfect sense!
