To the Green-Eyed Lovebird: We met 15 years ago, almost to the day, when I moved my stuff into the NYU dorm room next to yours at Senior House. You called us fast friends. I like to think it was more. We lived on nothing but the excitement of finding ourselves through music (you were obsessed with Jeff Buckley), photography (I couldn’t stop taking pictures of you), hanging out in Washington Square Park, and all the weird things we did to make money. I learned more about myself that year than any other. Yet, somehow, it all fell apart.
