Happened to me once, not very nice.
Same thing, high heels ( laboutins) lost my footing in them whilst hoovering and took a tumble down the stairs and through the front door as my other half opened it.
Ended up with a pair of black eyes, one from the door frame and the other courtesy of the wife when she came home unexpectedly and caught me in her favourite LBD.
She threw me out in the snow and left me to the mercy of a coven of fifteen year old school girls who subjected me to an hour of humiliation and beatings.
Get well soon Carol x
But you were doing the hoovering. Some people are never happy. She should have been happy you were pulling your weight with the housework.
