" But after all the years, her husband and children have come to accept that, once every few weeks, their usually warmhearted and approachable Camisha will get into her Honda Accord at the beginning of a seemingly random day, and disppear until well after supper, when she will return home and go directly to bed. Her family has learned never top ask her where she had been on such a day, because the most she will ever say is, "Out. I just went out for a bit."

Also, they learned long ago never to express irritation or anger of any kind against Camisha, because when they do, her reaction is to become mute and exit to the garden, where for several hours she will sit cross-legged on a favourite flat stone, her back to the house. Slender, straight-backed, and unmoving, at these times she resembles nothing so much as an elegant ebony carving, exquisite but not quite alive. Watching her is almost unberable, and so is the guilt. Or if the weather is not suitable for the garden, she will simpily go to her bedroom and lock the door. Then as a matter of course, without comment during or after, her husband sleeps on the sofa in the den. In the morning, Camisha is usually her old self again, just as if nothing had happened. "
