Or you could reset her clocks so she THINKS she's hoovering at midnight...rofl...

 

 

You never know, if you buy her a broom you may never have to hear her footsteps again...as she'll be using her brand new broom to fly with...

 

You shold find something equally loud to do at 11.59, like trying to hammer a nail into cherrywood (right next to impossible) or yes, get her a broom, but if its one of those high polish hardwood floors, get her a duster broom, the really big kind, I have one, they work well.
Or recommend her to jahovah's witnesses, they are more than annoying, let me tell you, some day im going to answer my buddies door covered in inverted crosses and pentagrams and watch them flee in terror, perhaps some dry ice in my clothes for a nice, sulphuric smelling smoke., some fake blood running out of my ears, that kind of thing, some Lamb of God (ironically) playing loudly in the background, lots of black canles and red lights, maybe a goat tied to a sacrificial looking peg in the living room....

LOL about the Jahova's Witnesses. My ex and his friends used to pretend they were having orges when they came to the door, but I like your idea much better.
