“There are some words I find impossibly difficult ... 'Love,' 'feeling' and especially 'happiness' are at the head of the list. This is not because I haven't experienced any of them but because whenever I think about using the words I don't really know what anyone means by them. I'd find it easier to sit down and write a book about each (coming, obviously, to no conclusion) than to use them casually in speech or writing.”
