Sara Zarrand i don't just mean that they change you. a lot of people can change you - the first kid who called you a name, the first teacher who said you were smart, the first person who crowned you best friend. it's the change you remember, the firsts and what they meant, not really the people......i'm talking about the ones who, for whatever reason, are as much a part of you has your own soul. their place in your heart is tender; a bruise of longing, a pulse of unfinished business.
