My name’s Irit Ziv. I have a low-rent apartment in the East Village that I used to share with my girlfriend, Shirley Chen. It’s April now, and Shirley died four months ago. Ever since then, I’ve been visiting Ma and Pa’s flat in Brooklyn Heights a lot. An awesome spot, with a full view of lower Manhattan. The trees by the river are turning green. I’m a grad student at NYU, trying to finish a PhD thesis in the physics department. Physics was probably a bad choice for me, but it’s too late to change.
