Usually our dog Flip wakes us when the daylight brightens up his hallway bedroom.
This morning it was the "mystery alarm clock" that woke both Flip and me. That blasted clock has been minding its own business for years and years in our living room, but today at 6:15 it went through the entire alarm cycle.
And who knows, maybe it has been "alarming" more often and I did not hear it until this morning.
Things just creak and pop and even ring when you have a house full of old things and old people ;)
