Prior to that, she asked me to show her how to drive the car, which was less successful and about which I was far less confident. Sitting in the passenger seat explaining how you drive is profoundly difficult, even when you've been driving - as I have - for twenty years. I managed to explain how to start the engine, and she started the engine. Then I explained about the gearbox and clutch, she put it into first, then I said the immortal words: "Just release the clutch now.."
It was a good job we were only on our driveway and there was nothing infront of us for 20 yards.
Teaching apparently consolidates your learning. I have heard people say that until you can teach something, you haven't learned it properly. I've had debates with my friend Lou over the years about whether I do teach the children. In the past I've denied doing any teaching at all, but I now realise that if asked, then I do try to teach - as sensitively as possible. And 'try' being the operative word. It's really not easy. I wouldn't try to teach unless I was asked.
And I stop when the person asks me to, or appears to lose interest - for example, last night Lyddie and I were reading Puddle Lane, when she asked how could the 'e' in 'pulled' be a magic 'e' and yet not be at the end of a word? So I explained about tenses, about which she was interested. I told her that some words change according to when they're happening and gave some examples. Then I realised I hadn't specified which words change under those circumstances, so I started on about nouns, verbs and adjectives, at which point she said: "Mum, can we just read the story now?"
Over-teach. It's an ever-present trap. It lures us in by the ego, and the triumphant sound of our own voices. I'm glad my children feel they can be blunt when they have to be.
Tom has been teaching me about electricity. I'm trying to understand how wind turbines work for our off-grid project and it's stretching my brains. It's one of those things I keep learning, but then forgetting and having to learn all over again. He uses Wikipedia a lot to explain things to me - pages like this, but I just look at all those equations and feel my mind start to frantically build walls to keep them out.
So I asked him to explain it more simply, and more simply, and more simply still. We got down to a metal coil surrounding a magnetically repelling material, like lead or graphite. I started to almost see how it might work then, but I still want to know why. When Tom had gone, I got out my old physics school textbook, but it didn't help. Some of the Dorling Kindersley ones on our bookshelves did though. ("Ages 8-14". What do they know?!)
So, you move something conductive within a magnetic field and you get an electrical charge. This I understand now, but I still don't know why. Does anyone know why? Tom keeps changing the subject when I ask him. I think.
