Harry Potter is, like, the gateway of fandoms, for me any way. You start reading the books, then all of a sudden you have a Sonic Screw driver, you're carrying salt everywhere in case Sam or Dean is in another room, intensely and emotionally invested in every Disney Story, ready to give up every thing and go along with Frodo or Bilbo, always ready to volunteer as tribute, to train beside Percy Jackson or defend your family honor in Game of Thrones, wishing every one to go with the force, praying you find a wardrobe full of Narnia and awkwardly obsessed with Sherlock and you don't really know how any of it happened, but you're pretty sure it started because Mr. and Mrs. Vernon Dursely of 4 Privet Drive were proud to say that they were perfectly normal thank you very much.
