"There isn't any sound in outer space," she said.

"Oh," I answered.

"There's no air out there."

"I knew that."

"Then why did you say, 'Oh, of course?' The engines. You can hear them all over the ship, it's a drone, all the time. That's just like the rain. Only after a while you can't hear it anymore. It becomes like silence. Anansa told me."

Another imaginary friend. Her file said that she had kept her imaginary friends long after most children give them up. That was why I had first been assigned to see her, to get rid of the friends. Grunty, the ice pig; Howard, the boy who beat up everybody; Sue Ann, who would bring her dolls and play with them for her, making them do what Elaine said for them to do; Fuchsia, who lived among the flowers and was only inches high. There were others. After a few sessions with her I saw that she knew that they weren't real. But they passed time for her. They stepped outside her body and did things she could never do. I felt they did her no harm at all, and destroying that imaginary world for her would only make her lonelier and more unhappy. She was sane, that was certain. And yet I kept seeing her, not entirely because I liked her so much. Partly because I wondered whether she had been pretending when she told me she knew her friends weren't real. Anansa was a new one.

"Who's Anansa?"

"Oh, you don't want to know." She didn't want to talk about her; that was obvious.

"I want to know."

She turned away. "I can't make you go away, but I wish you would. When you get nosy."

"It's my job."

"Job!" She sounded contemptuous. "I see all of you, running around on your healthy legs, doing all your jobs."

What could I say to her? "It's how we stay alive," I said. "I do my best."
