I had an okay sleep until 5:15 am when I woke up and was feeling way too warm in bed, even with the fan turned on. I knew last night it wasn't warm enough to turn the AC on, but at 5:15 I was questioning that decision. I visited the necessary and got a tiny bit more sleep, but never really got comfortable enough. So color me surprised when I got up later and found the house very chilly. Why had my room been so warm? Because what I should have done was open a window last night. I wouldn't have needed the fan, and the temperature would have been quite nice. Well, I looked at the weather, and I can do that the next few nights for sure.
