There was a noise in the lavatory. Someone had come in. Footsteps clattered on the floor. The door to the stall next to his opened and someone sat down.

He wondered who it was. The person wore plain brown shoes: he could see them through the foot-high space beneath the stall partition. This person also wore brown trousers. Richard Kuppelton thought for a moment, strained to remember who it could be. Then he remembered.

“Hello, Bob,” said Richard Kuppelton.

“What? That you, Dick?”

“The same.”

“You catching up on your reading?”

Richard Kuppelton closed his magazine guiltily. “No, no. Just nature.”

“It’s a good place to think.”

“Well, I suppose it is.”

“What’s wrong with Caroline today?” asked Robert Holton.
