There was loose, bulging linoleum on the floor. marian felt
as if she were walking on the waves, but the nurse paid no
attention to it. there was a smell in the hall like the interior
of a clock. everything was silent until, behind one of the
doors, an old lady of some kind cleared her throat like a
sheep bleating. this decided the nurse. stopping in her
tracks, she first extended her arm, bent her elbow, and
leaned forward from the hips-all to examine the watch
strapped to her wrist; then she gave a loud double-rap on
the door.
"there are two in each room," the nurse remarked over her
shoulder
"two what? " asked marian without thinking. the sound like
a sheep's bleating almost made her turn around and run
back.
