Mrs. Cuberle glanced up from her magazine.
"Hmm?"
"Do we have to wait much longer?"
"I don't think so. Why?"
Mary said nothing but looked at the moving wall.
"Oh, that." Mrs. Cuberle laughed and shook her head. "That tired old thing. Read a magazine, Mary, like I'm doing. We've all seen that a million times."
"Does it have to be on, Mother?"
"Well, nobody seems to be watching. I don't think the doctor would mind if I switched it off."
Mrs. Cuberle rose from the couch and walked to the wall. She depressed a little button and the life went from the wall, flickering and glowing.
