I went around the house today pulling all the storm windows down, and locking all windows tight to keep cold air out--and warm air in. I had to turn on the heat because it's supposed to drop to 34 degrees tonight. Then, I needed to go outside just a bit ago--and walked out thinking I had checked the door to make sure it was unlocked. Except it wasn't. I locked myself out of the house--and FI is out and about with our House Guest. I had no phone. And I had locked every. single. window. Luckily I failed at locking the window above the kitchen sink...but it was fairly high off of the ground--so I had to climb all over our deck furniture, and shimy my way up the side of the house into the window. Idiot.
