"Well, you did see me before."

"I did?"

"Yes."

"When and where?"

"Just look sharp and see if you can't place me."

"I can't."

"It was a great many years ago."

"It must have been; but to tell the truth, there is something very
familiar in your face."

"Yes, and you discovered it at the start, but you don't place me; I
placed you. I didn't until you mentioned your name."

"You now recall?"

"I do."

"Where have we met?"

"Try to remember."

"Tell me your name."
