I watch children a great deal; their idea is that rules are always negotiable, whereas you absolutely cannot joke at the airport about your toothpaste, and you cannot rollerblade in Grand Central Station. I keep running up against these things.
I created a successful outdoor youth festival - the Liverd festival - against all good advice. It was a great way to explore and investigate social sculptures. Having that as my kind of studio, outside of a museum or precious white-cube gallery, that was a kind of education.
