I have just met some enthusiastic teenage students from a workshop I ran a few months ago. Hang on, I say, I have something I wrote about you in my diary - let me copy it out for you. The diary turns into a comic with action hero adventures. I copy the relevant text, furtively editing out the bit about my fancying one of them. As I do so I question the whole process. Why am I giving it to them? Why on earth should anyone want to read these edited notes from my diary?
