Some of her enthusiasms mystified me. As we sat in the theater, sharing a giant chocolate bar, I kept wondering why she had wanted to see a double feature of old Katharine Hepburn movies, both of which she said she’d already seen more than twenty times. Of course, she was besotted (another favorite word) with moviegoing — in the way, perhaps, that only someone who never watches television can be. (We know this now: if one size screen doesn’t addict you, another one will.)
