About 02:30 this morning, while dead asleep, I was awakened by some noise. The cats all leaped up at the same time that I sat bolt upright. (The cats were all curled up around me, so it wasn't one of them — which it usually is — which made me worried that perhaps someone was breaking a window or something.)
I got up and proceeded to turn on lights all through the house trying to figure out what noise had awoken me.
After five minutes of this, I finally "mentally replayed" the sound I'd heard and thought, "Gosh, that sounded like something falling in a bathtub or shower." I checked the bathtub — nothing. But in the shower, there was a conditioner bottle lying on the floor.
How does a conditioner bottle that sat, stable on the shelf, for 19 hours, suddenly fall off in the middle of the night?
(This is why I'm a little groggy today. That's my story and I'm sticking to it.)
