If I were young, he'll be mine

As she was studying to be a social worker, Sandy, 19YO, met a lot of students from different ages as some of her classmates were coming back to studies to change career.
One of Sandy's classmates, Marie, was 48 YO. And when Sandy showed her boyfriend, Cédric, during a student party, Marie told her "He's very cute ! If I was young again, I'll steal him from you".  It was only a joke back then. But, some months later, Youth Days Phenomenon appeared.

And then one day, Sandy received a picture from Marie, showing her youthful appearance with a text saying : "I'll be to the student party tonight. Will your boyfriend be here ;-) ?". Sandy asked herself if it was a joke and if it was really prudent to take Cédric with her tonight.
