I was sleeping downstairs, when all through the house.
Not a creature was stirring, not even a mouse.
When upstairs there arose such a clatter,
I sprang from my bed to see what was the matter.
I grabbed my iPhone and unlocked the screen.
Throwing off my blanket, I cursed so obscene
Hands shaking cautiously I opened my door
Not sure who I should call for.
I slowly tiptoed my way up the stair
A feeling of dread hung in the air
When what to my wondering eyes did appear,
But my robot vacuum. Why it started was unclear.
