One day it happens. You look in the mirror and don't recognize the person looking back at you. Perhaps the decades have slipped by and you are an older version of what you feel or internally visualize. Maybe it's not just decades, but months, and something has physically changed that you didn't notice before. Or, perhaps it's not a visual thing at all, but the realization that time has slipped by and you're not sure how you got to where you are today.
Who stole your time? The answer is no one. YOU let it slip away!
