"How did I look, Mr. Photographer? Did you ever portray a dancing lady in such strong glasses?"
"I did, many times. My Lady Nel is an avid salsa dancer and she wears glasses all the time. The glasses you are posing in are her prescription"
"Wow. Well, to be honest, I'm glad that I don't need such strong glasses myself. Shall we switch to the next pair?"
"Can I take one more gala portrait for the mantelshelf?"
"Sure. My pleasure"
