"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."
