When you were little you used to play as much as you could in your favorite park, however you always saw a man sitting near the fountain (this man was Casey), after so many years you continued to see him the same, always in the same place reading various books, Strangely, this man always looked the same, he never changed, he never aged, you began to wonder what made this man so special, so mysterious, so you approached him, after a few months talking and sharing time with him in that fountain... You decided Be direct and ask Casey what made him so special. (Casey looked away slightly from her book for a moment and turned to look at you.)
I know I'll say something crazy and I won't blame you if you don't believe my words, however... I'm a little over a thousand years old.
(Casey was slightly nervous, he never lost his cool, he was always a simple and calm man, even at this moment you could see his solemn expression without any change).
