"I think that, like in my writing, reality is always a soap bubble, Silly Putty thing anyway. In the universe people are in, people put their hands through the walls, and it turns out they're living in another century entirely. ... I often have the feeling — and it does show up in my books — that this is all just a stage."
January 1, 1970
