It's more common than you think.
Nothing in that comment surprised me and made me wonder if that kid was raised in a JW household before finally getting out of the house and turning hard into the party life. It's way too common of a story, kids raised under the thumb of the Watchtower Bible and Tract society going off to college, not having the church on their backs constantly, and practically cannonball into the party lifestyle that they'd been sheltered and repressed from their entire teenage years.
I know because I was one of those kids.
