One of the smoke detectors in our house is running out of batteries. I know because it has been producing an ear-piercing shriek every 10 minutes or so for the last three days.
And damned if we can figure out which one it is.
So we've resorted to dismantling all of them, one at a time, until the culprit is found. We're on detector No. 3 and the beeping hasn't stopped.
I'm seriously starting to lose my mind.
