taking the leap

Joel sits at the far end of the empty car and watches the
slowly passing desolate terrain. After a moment the door
between cars opens and Clementine enters. Joel looks up.
Clementine is not looking at him; she busies herself deciding
where to sit. She settles on a seat at the opposite end of
the car. Joel looks out the window. He feels her watching
him. The train is picking up speed. Finally:

CLEMENTINE
(calling over the rumble)
Hi!

Joel looks over.

JOEL
I'm sorry.

CLEMENTINE
Why?

JOEL
Why what?

CLEMENTINE
Why are you sorry? I just said hi.

JOEL
No, I didn't know if you were talking to
me, so...

She looks around the empty car.

CLEMENTINE
Really?

JOEL
(embarrassed)
Well, I didn't want to assume.

CLEMENTINE
Aw, c'mon, live dangerously. Take the
leap and assume someone is talking to you
in an otherwise empty car.

JOEL
Anyway. Sorry. Hi.

Clementine makes her way down the aisle towards Joel.
