When I was in the supermarket doing the Christmas shopping last week I bought one of those dusters. You know, one of those special synthetic cloths that are 'static' and 'magically' pick up dust. It even had a special plastic cover (so it didn't zoom into action when you didn't want it to?) with a little hole so you could "feel the special surface". When I got home and as I was putting in in the hot water cupboard, I noticed that there were no fewer than five! (count 'em, 5!) others of similar ilk that I had purchased previously. Why then do I still have such a dusty house!?!
