Olave Baden-Powell, Lady Boden-Powell, or even The Dowager Lady Boden-Powell, as I believe her bezzies called her. Haven’t heard of her? Sorry but that must make you a girl-guiding idiot. Not an idiot girl guide, but an idiot to the world of girl guiding. (Sorry, you, dressed in blue, please don’t take it the wrong way and carry on with your knotting practise so no one else calls you a girl-guiding idiot).
