The Doctor looked wryly at his guest. He knew David had not gone home after running away.
"Did you see Mother after you went back?" he asked.
"No, I didn't see her."
"But you are sure you went back?"
"It didn't feel back," said David.
"You couldn't have been mistaken about going back?"
"No."
"In what part of town were you when I found you on the fence-post?"
"Home," said David.
