"Imagine for a moment playing by children's rules. If you were at a party and saw someone you liked, you could just go and hold their hand. If they then try to kiss you and you don't like it, you can push them over. If your aunty gives you a Christmas present that you're not too keen on, you can throw it back in her face and burst into tears. You can gallop freely. You can skip. Children have got it right. The tragedy is, none of this is permissible as an adult. Although one thing surely is – and I'll bet you know what I'm going to say – that's right, the galloping. Such fun!"
