We have several ghosts in this house.
1. The one that knocks the shampoo bottles off the shelf in the shower.
2. The one that has made the sun room smell like sesame oil.
3. The one that makes an electronic beeping sound somewhere under that pile of paper, just over there.
4. The one that lives in the light above the kitchen table that the cats stare at for hours on end.
We’re learning to live with them all.
Apart from the beeping one (although that may be feasible too), your ghosts might all be ghost-cats and your cats see the light on over the table as a ‘sign’ telling them to knock over more shampoo bottles…
I know. Work is boring today.
