My mum once left me a message that was far too technologically advanced for me. It was back in the days of answering machines. She was out when I got home and only when she returned did I find out there was a message for me on the answering machine – I was supposed to know this by means of the tiny red blinkenlight, play the message and discover that dinner was in the oven, or whatever it was. It would have been simpler and more effective to leave a note on a piece of paper, but hey, it's a hungry world when you're a teenager with technosavvy parents. Or something.
