"Fine, which years would you like to offer?"
"Huh?"
"You appear to be a successful businessman, do you really wish to give up the last few years of your life? Or would you rather give up your high school years, when you were mocked in gym class and had to take your aunt to the prom?"
"How did you know about th--? You mean, I can pick the years, I give up? But will I be younger?"
"Of course, you'll be younger, but there are other considerations. If you give up your 18th year, you won't have taken your aunt to the prom, but you won't have given the Valedictory speech either--let alone graduated from high school."
"If I chose the year I got married and the year I got divorced?"
"Well, if you chose the year you got married, you'd never have gotten divorced at least not from the woman you married that year. Your life would be different. You might have married someone else, or --?" Madame raised an eyebrow knowingly.
The young man shifted his feet trying to decide.
"Choose your years carefully?" she advised.
"Okay, I've decided."
The little boy smiled in anticipation, he was finally going to grow up.
