Best Beloved use to work in Saudi Arabia, and she picked up one of these nifty little numbers for getting about in public.
It's astonishing. The woman you love is standing a few feet away from you and her identity has vanished, subsumed into a surprisingly light and airy black cloak. (Well, it felt light and airy to me, but she said she was sweltering even under the lights in our room.) She has been erased.
If I can use the language of one religion to describe another, it's been an epiphany. And not a nice one.
