How we cite our quotes: line
Quote #1
But we looked into a fire, we leaned across a table,
We lay on a hill-top underneath the moon;
And the whistles kept blowing, and the dawn came soon. (3-6)
The speaker emphasizes the "we"-ness of the actions she remembers, making sure that the reader knows that everything that happened that night was done with "you."
Quote #2
We had gone back and forth all night on the ferry;
And you ate an apple, and I ate a pear, (8-9)
The syntax of line 9 feeds into the sense of shared actions set out in lines 7 and 8: the repetition of "and" allows the speaker to describe each individual's actions as if they were part of a related whole.
