This morning I woke up to PEEP....PEEP..... PEEP! I think the smoke alarm battery is going dead. And I get out of bed slightly and hear it coming from the left of the bed... there's no smoke alarm there, so I sit up wide awake thinking the neighbor's house alarm is going off. I go to the window and tilt my ear and look around furiously, then I hear it coming from the other window... it's really loud now PEEP....PEEP..... PEEP! Standing at the other window it sounds like maybe it could be driving around the neighborhood. I wonder if a small bulldozer is backing up somewhere... I can't really tell where it's coming from... I sit down on the bed and wonder if I should investigate further. My young child rolls over, it is then I realize... it's his nose whistling while he sleeps.
