Why Are We Even Doing This?

I don't know much about how I arrived at the orphanage, except that it had to do with something called the Wizarding War. I'm not sure of my full name, but I know who I want to be. I can't stand this place, but I know there is a way out. The certainties in my life are limited, but I know that when I figure it all out, I'll want Ron by my side.
