Read the passage from a raisin in the sun.

ruth (looking up at her and smiling): . . lord, that man—done changed so 'round here. you know—you know what we did last night? me and walter lee?

beneatha: what?

ruth (smiling to herself): we went to the movies. (looking at beneatha to see if she understands.) we went to the movies. you know the last time me and walter went to the movies together?

beneatha: no.

ruth: me neither. that's how long it been. (smiling again.) but we went last night. the picture wasn't much good, but that didn't seem to matter. we went—and we held hands.

beneatha: oh, lord!

ruth: we held hands—and you know what?

beneatha: what?

ruth: when we come out of the show it was late and dark and all the stores and things was closed up . . and it was kind of chilly and there wasn't many people on the streets . . and we was still holding hands, me and walter.

beneatha: you're killing me.

how does the playwright develop the theme "it can be difficult to keep romance alive in a marriage" in this passage?
