I agree totally Angel. It is sometimes funny just how wrong people can get it, which is partly why I do not explain my work.
I once studied photography, and we were given an asignment to produce a series of abstracts. I was the only one in the class who refused to explain my work. When I explained that any information on what the photos were of would turn them into pictures of something rather than abstracts the teacher agreed and gave me an A.
This really annoyed the rest of the class who had all explained their work and subsequently lost marks because of me.
