She felt a constriction in her chest, like a steel band tightening. Her head swam. She blinked rapidly, as if that would somehow make the words disappear. Her hands, clammy and cold, went to her mouth.

He came in, humming. "What's up?" he asked. She looked at him, at the face she thought she knew, and felt a disorienting sense of unreality. The question bounced off her. She could only shake her head, the words stuck deep inside.
