Michael and I talked a bit about how "bark" falls from gum trees, and is also the sound dogs make. He thought it was interesting, and mulled it over for a while, talking quietly to himself. We were at the park, sitting with some leaves and bark and bits of cardboard we had found, which he started to arrange on the table. He said "I am making a dog from bark". Making a Dog from Bark sounds like an event at the Surrealist Olympics.
