Jerry takes a deep and meaningful drag on his cigarette, crosses to the window and says...
"Shall we just have a cigarette on it?"
Charlotte moves toward Jerry, takes the cigarette he has lit for her, inhales deeply and says (with tears in her eyes):
"If we work hard to protect that little strip of territory between us....(etc, etc)"
Jerry, eyes filled with tears, exhales and asks:
"But will you be happy, Charlotte?"
Charlotte, fighting back tears and acrid cigarette smoke:
"Oh Jerry, Let's not ask for the moon.....we have the stars"
This movie was one of the best examples of the use of cigarettes as a third character. The character here being sex, of course.
"My dreams, watching me said, one to the other...this life has let us down."
