I am beginning to think I may have ...
... a Poltergeist!
First my freezer drops dead, then the 'fridge, then the ice cube maker. This morning my computer CD player said it 'couldn't read' the disc that played perfectly well yestermorn, and now - just come back from shopping and found a picture that was hanging peacefully on the wall when I went out - sitting on the sofa!
The cats were cowering behind an armchair - when I asked them about the painting they spat at me and fled - last seen on top of the wardrobe in the bedroom!
Help - somebody send for an exorcist!
