Welcome to my profile thingy. I suppose I should just start with introducing myself so we can get that out of the way. In light of that: Online I go by DutchSlytherpuff, because I am Dutch and my two favourite Houses are Hufflepuff and Slytherin. That wasn't always the case, though. When I was younger, and Pottermore was new and still exciting and fun, I took the original Sorting Hat Quiz. Back then you could be a Hatstall and then you had to choose between the Houses it thought would fit you best. It gave me the choice between Hufflepuff and Slytherin. At the time, I was pretty firmly anti-Slytherin. I was young so I had this idea that Slytherins were just... well, evil. So I chose Hufflepuff. In my mind back then, it seemed better to be dumb (as I thought Hufflepuff was) than to be evil.
That was over a decade ago, and a lot has changed since then, not least of all my understanding of the Houses, but the name has stuck. As has the fandom. I remain obsessed with Harry Potter and I don't see this changing anytime soon. Harry Potter will always be an important part of me, and always has been, though it's hard to say exactly when or how it started. I didn't grow up as the books were being published, but my mother did read them to me and my brother when we were quite young, and I do know I liked them from the start, though my obsession didn't start until a few years later, after I'd heard, watched, and read them all in my native language.
Since then, I have read the entire series in English more times than I can count. I've also read them a fair number of times in my own language, as well as once in French and once in German (I had to learn these languages for school; what better way to practise than by reading Harry Potter?) and I still want to reread them in those languages sometime. I find that reading it in another language adds something to the whole experience.
