"When you make something, if you are a painter or a writer, a degree, or a sculptor or whatever or a musician, a degree of energy is required to make it, and I'm not sure that it is always aggressive, but when you have a great deal of energy it can appear to be more aggressive than it is. In fact, I mean you can talk about a waterfall being aggressive, but in fact it is just a very powerful forward movement of energy, and although I think sometimes my engine house is a kind of anger."
