When she was 5yo, my sister was always terrified of Santa Claus...

Confused, my parents asked her why she was afraid of the day she'd randomly wake up to gifts & candy.
Her response makes so much sense that I felt dumb for NOT being scared:
Sure Santa brings gifts. But his presence in our home highlights a systemic issue that poses a threat which I'd gladly sacrifice my gifts to fix.
Each year that Santa manages to bring gifts without 1 of us catching him is a year in which we failed to protect our home.
If an old, overweight guy can fall through the chimney unnoticed, a professional burglar can get in our bedroom any other night too.
