True or false youth ?

Since Youth Days happened, one of Medhi and Charles's favorite activities was to guess the true age of the women they saw. Sitting in front of a chicken at a KFC, they looked around, searching for a new target:

"Her !" said Medhi, "the girl in mini shorts at the machine!"

- Seriously? You think an old woman would dare to dress so sexy ?!
- Precisely: she has been stuck all her life and takes advantage of her new youth to the maximum. Oh look! I think that is her daughter! "

Another young woman had just approached the first. From where they were, Charles and Medhi could hear her dispute her "mother" for the outfit she wore.

"Well played guy, you're strong at this game" congratulated Medhi. "it's a fake young girl".
