He followed Clayton’s motions with a singular interest in his reddish eye. "that’s not bad," he said, when it was done. "You really do, you know, put things together, Clayton, in a most amazing fashion. But there’s one little detail out."

"I do not see I can do any harm in telling you just the proper twist. After all, if you know, you know; if you don't, you don't."
