Many years ago there was a wonderful little kitchen tool on the market called an autochop. It consisted of a small tub with a chopping blade inside and when you bashed on the handle a few times the blade would descend, rotate, and duff up whatever was inside. I used to keep it on the worktop, and on fridays when a particular pupil had finished her lesson I would race into the kitchen and autochop a welshcake or two! She lived about two hundred yards away, always "forgot" her books and had to back home for them, always wanted to go to the toilet as soon as she arrived, and didn't do much practice either! But she and her parents always insisted that she loved coming for lessons and really wanted to play the piano. I sorted out the book problem by telephoning her five minutes before her lessons to remind her to bring them, and the loo problem by telling her on one occasion that of course she could go to the bathroom if she wanted, but that I had seen a big ghost on the stairs the day before. (Nasty wasn't I!) We never reaally got over the lack of practice problem as she was happy to do a little occasionally and was also quite happy with her own progress. Ah well. Happy Days!
