I loved all of the Harry Potter books dearly, especially Harry Potter and the Sorcerer's Stone, which opened this whole new world of fantasy and imagination for me. You know how reading a book takes you into a world which you have trouble leaving when you have finished reading it? I didn't want to leave the world of Harry Potter when I had finished reading the series. I had Harry Potter in my mind almost all of the time. I went through an incredibly long phase of being obsessed with Harry Potter. I had read all of the books by J. K. Rowling (except for the fourth one), seen and loved all of the movies with Daniel Radcliffe as Harry Potter, Rupert Grint as Ron Weasely, and Emma Watson as Hermione Granger. By the way, I used to think her name was pronounced Her - mi - own, instead of Her - mi - nee. When I began to get into watching the films, I realized her name was not pronounced like that. So from then on, I pronounced her name differently in my mind when I read the Harry Potter books. Her character never felt exactly the same for me after the change in pronunciation, though. It's funny how much a name helps to create a character.
When I was younger, I would often wish I could receive the letter of acceptance to Hogwarts, School of Witchcraft and Wizardry. I even designed the kind of wand I would want to have, what sort of owl I would like, and what house I would be in. I've always wanted to be in Ravenclaw, but I think it more likely I would end up in Hufflepuff. I decided I would want to play Quidditch, and fly on a broom. I even imagined meeting Harry Potter, Ron Weasley, and Hermione Granger. As Harry Potter grew up and the films continued, I grew up. It was as if the Harry Potter series grew up with me. This made Harry Potter a large part of my childhood. When I turned eleven, the letter never came. To this day I still wish I could go to Hogwarts and be a witch.
The world of Harry Potter never left my mind. I'm not "obsessed with it" any more, but the story, the characters, are all in the back of my mind. I would say despite not reading a Harry Potter book for a long time now, and not seeing any of the films in a while, I am still an expert on the subject of Harry Potter. Watching any of the Harry Potter movies, even a short scene from it, will bring it all back to me.
