Callie Rose is 13 Double science was fantastic today – 'cause I got to sit next to him. Of course, when Mrs Mayne split us into pairs and said we had to work together, he moaned like the north wind down a chimney about having to be my partner. But then he had to do that – otherwise his friends would've teased him about sitting next to me and working with me. But I bet he was just as thrilled as I was. I got to sit next to Amyas. Yippee!! I know I didn't like him much when he joined the school, but since then he's got really buff and become knock-down yummy on a stick. And I've grown up in a year. Grown up a lot. I can appreciate boys now – well, some boys. Well, one boy. 'I'm in charge of this experiment and I'm going to do all the mixing. You can write up everything,' Amyas told me. 'OK. Whatever you think best.' I smiled. Not too many teeth, smile with the mouth and the eyes – I read that in Ms Young Thing magazine two weeks ago (How to Win His Heart With a Winning Smile – Part 1).
