Had barely started work when another knock came at door. Miss Marple on doorstep proudly holding a "Neighbourhood Watch" window sticker. Reticently accepted it and was in negotiation as to where it should be placed when postman walked up to provide pile of letters (having not seen him yesterday). When he had sauntered off Miss Marple whispered she thought he was a "rum character", which took to mean she didn't like him. Went on to say she wondered why Andy had been replaced. Said I didn't have a clue, and invited her in for a cup of tea.
At Miss Marple's insistence placed sticker in centre of lounge window, all attempts at suggesting otherwise rebuked. Sure other half won't mind - it's for security.
