That's Magic!

I came home from work tonight to find that the dishwasher had been emptied, my bed had been made, the kitchen had been tidied and the computer had a new screen saver.
I know it wasn't me or the missus cos when I'm on late shifts I'm bone idle. Truth be told, I'm lazy when I'm on earlies too. And, the missus is on nights, which means she has less time for housework than I have for Tottenham.
The only thing I can assume then is that there's magic in the air.
Either that or my lovely sis-in-law Michelle did it while her layabout fella watched the footy.
THANKS LOVE!
