Making Room

The author keeps this Navajo chant taped to her back door.

To rent rooms in your house, you’ll need to throw away the images of television housemates in “Friends,” “Golden Girls” and “The Big Bang Theory.” Those depictions are fantasies, entertaining as they may be. You don’t need to eat together, host parties, go on outings, shop for groceries, or hang out at the coffee shop with them.
