I've always been convinced that people are obsessed with putting stuff in/on any available space. Even if they have no stuff to hand, when they see an empty vessel, or bare table/clear worktop, or floor void of furniture, they will go and search for stuff to put in/on said space!
I have commented on this to Mrs. Map and all the Maplettes on numerous occasions, but they all reply with the usual 'ptfft'! (Dad on one of his missions again!)
So this evening, before I left for my gig, I put an empty bread basket on top of the microwave oven. Upon my return it contained TWO cameras, a Calculator, a Bracelet, two Dress Rings, a pair of headphones, a keyring and half a bag of Hulahoops (a spud based snack!)
I rest my case! (Remember, I am the only male in a family of five!) :¬)
