Since Mother Eve in the Garden long ago

I really thought this rabid Dan Stevens anti-fan I'm bickering with on Tumblr was going to turn out to be sixteen, seventeen like the poor kid I accidentally disagreed with into deleting over an 18th century clothing debacle (although in fairness, she did mega-condescend to me when I first responded to her). Nope, she appears to be at least a couple of years older than me.

I thought this only happened in Harry Potter fandom.
