Today after walking the dog, getting the Telegraph, then doing the local market shopping I decided to blitz the house exterior. Clearing the gutters, brushing off mould from the facia boards, washing & scrubbing all surfaces, windows etc. After six hours I stood back in the afternoon sun admiring my efforts. My wife returned soon after I'd finished... from a shopping trip.... and enquired without batting an eyelid: "Have you done the hoovering?" Is it in their DNA?
