Because Australia is so far away, expensive and entails spending a large chunk of time, coming to Australia is a radical move. No one says, "Oh, I am going to Australia for the weekend, or to do some shopping or to go to a concert." Coming to Australia is radical.
Everyone on the tour had their stories. From the recently bereaved young man who lost his mother to cancer, to the mature nurse starkly adapting to her changing world. Some escaping, others embracing. I am always--without exceptions--encouraged when I meet people. There is so much energy and truth in what we do. Sitting at home constructing our reality inevitably leads to negative interpretations because we tend to remember negative events better than positive ones. We have more words for negative emotions than positive ones. But in real life, the life of people interacting, there is mostly positive energy. We are truly social beings and anything that impedes our ability to interact socially is cancerous. It's all Good.
