Like most music that affects me deeply, I would never listen to it while others were around, just as I would not pass on a book that I especially loved to another. I am embarrassed to admit this, knowing that it reveals some essential lack or selfishness in my nature, and aware that it runs contrary to the instincts of most, whose passion for something leads them to want to share it, to ignite a similar passion in others, and that without the benefit of such enthusiasm I would still be ignorant of many of the books and much of the music I love most... But rather than an expansion, I've always felt a diminishment of my own pleasure when I've invited someone else to take part in it, a rupture in the intimacy I felt with the work, an invasion of privacy. It is worst when someone else picks up the copy of a book I've just been enthralled by and begins casually to thumb through the pages.
