Morning but only for a short time, I hope. Our smoke detector started chirping low battery. Replaced them and trying to convince the brain we really need to go back to sleep.
Happened to me the last time I was home.
Waiting for the rest to do the same. LOL. Actually for some reason this one had a cheapo battery in it. Can't remember why but I find 2 more 9volts stashed for just this reason.
