"Hey Mr. Photographer, did you notice that this is our last pair of glasses?"
"You are a polite young lady by putting it that way, Iris. I realize that time is up. You selected some more glasses and they are still in a box on the dinner table. Any chance that we do another photo shoot with those glasses?"
"Well, I might be persuaded. How about one final photo?"
"It will be my pleasure, Iris. Just choose any pose you like"
