Yep, it’s one of those days.
I woke up at 4am (0400 for non-USA people), needing to go to the bathroom. Expecting to get up at about 5am anyhow, I turned on the furnace to pre-heat the house (it was off overnight), and stumbled into the kitchen with my eyes half-open to turn on the coffee pot. I thought there was still one or two cups of coffee in it, and this would have the coffee nice and warm when I got up later.
Then I went back to bed. At 7am, my wife shakes me and says she’s getting ready to leave for work. Oh, by the way, did I know that the coffee pot was empty when I turned it on? The whole kitchen now smells like burned coffee. Fortunately, it didn’t actually break the pot.
