Like most parents, I've been stumped by homework, the big questions, such as: 'What is the point of geography - the pilot always knows where we are going?'. Answer: 'If you didn't know any geography, people would think you were an American, and you wouldn't be able to put them right because you wouldn't know where they live.'
An American has invented a remote control that will turn off any telly within a 20ft radius. What a marvellous device! What a splendid invention! What a really helpful and improving way of devoting your time to building something that turns off culture. Next week, I'm instigating Burn a Book Week, to encourage even more conversation. I've come up with a fantastic little device which I'll call a box of matches.
Science fiction is never about the future, in the same way history is rarely about the past: they're both parable formats for examining or commenting on the present.
