DH said that he was awoken by a chirping sound at 2 a.m. on Saturday morning. He tracked the intermittent chirping all over the house until he finally figured out that it was coming from the smoke detector upstairs, telling him that the battery was low.
How come smoke detectors always wait until the middle of the night to let you know they're about to die? Is that something designed by the engineers to give them a chuckle on slow nights?
