And, you know, stumbling about in the dark (with no glasses, as I broke them the other day and am using daily contacts until they're fixed), attempting to find the source of the chirp? Is endlessly amusing to the cats.
I make it to the lounge. Stop. Listen for the chirp. Move to the dining room. Stop. Listen for the chirp. Look suspiciously at the alarm panel. Stop. Listen for the chirp. Tilt head like Illyria. Stop. Listen for the chirp. Grimace with hope. Listen once more, look for fuzzy red flash. Determine source of noise. Now what?
So then I return to bed (with amused and hungry cats), attempt to get back to sleep, wonder how Ben can not even wake up, eventually give up, and get out of bed and turn on the computer.
Isn't it weird how it's definitely a chirp, though? It's not a beep, or a buzz, or even a chirrup. It's a chirp. Endlessly. Every DAMNED minute.
They always decide to go flat in the middle of the night, too. Is there a Murphy's law for battery-operated appliances?
