I feel I need a holiday, a very long holiday, as I have told you before. Probably a permanent holiday: I don't expect I shall return. in fact, I don't mean to, and I have made all arrangements....
I feel all thin, sort of stretched, if you know what I mean: like butter that has been scraped over too much bread. That can't be right. I need a change, or something.'
