Slytherin House, house of the cunning and ambitious, has been given a bad rap through the series. A majority of the Death Eaters came from Slytherin including Voldemort himself. The Slytherins are often seen as the "bad house." This is just not true! Slytherins are some of the greatest people you will ever meet and some of the greatest friends you will ever have. It's important to note that I myself am not a Slytherin but a Hufflepuff. That being said, I cannot deny that Slytherins have made up some of my closest friends.
Slytherins can be great leaders. While Hufflepuffs are oftentimes too busy trying to make everybody happy, Slytherins are the ones who will actually get things done. Every squad needs a leader, someone who can organize everyone so were not stuck in one place all night trying to figure out where to go. Sometimes you need a Slytherin around to help make decisions.
Slytherins are also known for being very protective of their friends. You might not always it, but Slytherins always have their friends' back. The reason you don't see it, they know how to get revenge on whoever was bothering you without getting caught.
We can't forget brutal honesty as an important trait with Slytherins. While it might not be fun to hear, Slytherins are only honest because they care. If you ask for an opinion on the outfit you're think about buying, they will be completely honest if it doesn't look great. They don't do it to be mean, they do it because they care.
Finally, Slytherins always try to encourage you to be your best. Slytherins are the friends who push you to do something you want, but are too afraid to do. They are the friends who will tell you that you have talent and encourage you to use it. Slytherins will not take excuses for why you won't try for your dreams because they want to see you happy. Slytherins can be the greatest friends you will ever have because they can make you a better person.
