When I was 13 my father and I spent a month in Australia. As we traveled around we shared about Winslow Cohousing, where we had been living for the past two and a half years. At our first presentation my father did all of the talking, and I pointed things out on our slides. By our last presentation, before 400 people at a Permaculture convergence, I did all of the talking, as well as pointing out things in the slides.
