Websites or similar that have sorted you into Slytherin: I've been sorted into Slytherin at hp-fc.de, one of Germany's largest HP communities, furthermore on a test on Facebook and various other quizzes at Quizzila etc.
In your personal opinion, what makes a Slytherin: Ambition, Independence, Slyness, Loyalty towards your friends.
Choose one stereotype about Slytherins that you believe is unfair, and tell us why: Slytherins are always the bad guys. I think it's not fair to judge them without considering the other side. As an example you may take the situation before the battle of Hogwarts. Noone offered the Slytherins to actually join the "good" side and fight against the Dark Lord while among the Death Eaters were many friends and family members of the Slytherin students. Therefore I think it's quite natural that they chose to leave. It's always been everyone against them and I hardly doubt they believed they would be honestly welcomed in the DA or similar groups.
What personal traits make you well suited to being a Slytherin: I think I'm a two-sided person. There's the real me and the person I often use in public. It's quite easy for me to put on a mask and appear like a shy, polite, helpful and charming little girl to get my way. I'm intelligent and know my strengths and weaknesses, and I know how to overcome them. I tend to use people for my purposes, which doesn't mean that I don't feel any affection for them. I'm loyal towards my friends and family, but if someone gets in my way I know no pity. I can be as arrogant as hell if I don't like someone and this person has no use for me. I have standards. I don't have to stand everyone just because they would like me to. I decide by myself which people I allow around myself. I'm independent and prefer doing things on my own because I hate people telling me what to do. Especially if they think they can order me around and have no idea what they're actually talking about. Furthermore I tend to be impatient with incompetent and stupid people, they only waste my time. Time is precious because I'm ambitious concerning things I care about, and I want to be the best at those activities.
Describe something you've done that you consider Slytherin-like: A couple of years ago we had a teacher at school who was disliked by the whole class. She was incompetent and gave grades according to whether she liked a student or not. The latter was normally the case. I didn't learn anything new that year and I honestly wanted to throw my history book at her because she was such a fool. Instead I was polite, greeting her with a smile every time I saw her and tried to charm her. It seemed to work. I got the best grade of the whole class. Some of my fellow students accused me of being fake afterwards, but honestly, I don't care. There's no point in ruining your average just because you can't stand a teacher.
What, in your personal opinion, is a Slytherin's code of conduct: I guess there are a few, but I'd say Think before you act. And be aware that sometimes it's better to keep your thoughts to yourself instead of blurting them out..
If you couldn't be in Slytherin, which other house would you be in, and why shouldn't you be in that house in the first place: Although it might sound contrary: Gryffindor; because somehow they follow their own rules to be able to do want they want. But I think Gryffindors tend to be too bold and act before thinking, which is not quite my way.
Explain in less than 500 words why you wish to join slytherin: I've never considered joining another house because I've felt some kind of bond with Slytherin from the beginning. And if the Sorting Hat would ever dare sending me to a different house I would open the depths of hell for him. From joining this community I hope to meet other people who share the same principles in life and who feel the same affection towards the house of Slytherin as I do.
