Perhaps I'm particularly serious, because I'm not unaware of the potential absurdity of what I'm doing.

I'm a little bit perverse, and I just hate doing the thing that's the most obvious.

Quite honestly, if I were doing work related to a living being or historical being where there was visual or audio recordings available, I would find that extremely difficult because I don't know how you would avoid the process of mimicry. And mimicry, to me at any rate, is a very dull prospect.

There is an absurdity in it, particularly in the relationship between the siblings.

In all fields of creativity you see the result of work that has become habit. Where the creative impulse has become flaccid or has died out altogether, and yet because it is our work and our life we continue to do it.
