A couple days ago, I woke up at 3:30 a.m. to hear an intermittent beep from one of our smoke detectors. I stumbled out of bed and grabbed the last of our 9V batteries, hoping I could fix it before the noise woke my wife and/or my daughter. To make sure I was replacing the right one, I stood under the detector in the hallway, waiting for it to beep. I think the detector knew what time it was and wanted to mess with me. It was a full 5 minutes before it beeped again.
I ripped the thing out of the ceiling and replaced the battery, crossing my fingers my brain hadn't woken up enough to keep me from going back to bed. I got it back up in the ceiling and fell back into bed with a sigh. No sooner had my head hit the pillow than another smoke detector started beeping. We didn't have any more batteries, so I tried in vain to tune it out. That lasted about 2 seconds, and my brain started going through my day, thinking of all the things I needed to get done.
Bottom line: I was in the shower by 4:30 a.m. and felt like the walking dead all day.
I felt a bit like this (brace yourself for one swear word):
