In 2005 I liked to use the IGN Legend of Zelda forums to discuss/hype the upcoming release of Twilight Princess. I was chatting with some random on the social off-topic thread and name dropped my small city, turned out he lived there, and going further down the rabbit hole we turned out to be classmates 1 year apart. I even asked him some obscure things only somebody who went to my school knows, it was legit.
