Does a House truly define who you are?
 

There is no question that someone's Hogwarts house plays a very important part in their time at the school. But the question is: does someone's house truly define who they are? Or is there a lot more to it? What about people who could be sorted into more than one house, like Harry Potter, who could have also fit into Slytherin?

Or are houses not really all that important in shaping someone's identity at all?
