Quote #4
His face had darkened with shame at having his pleasure aroused in public by one of his daughters. [...]
"That's enough of that," he commanded in a low, furious voice. (1.2.65-66)
So this suggestion of incest has been present throughout this entire chapter. There's been lots of subtle father-daughter flirting, and Papi even seems jealous of his daughters' husbands. But when Fifi gives Papi a "wet, open-mouthed kiss in his ear," she goes too far.
Quote #5
The mother dressed them all alike in diminishing-sized, different color versions of what she wore, so that the husband sometimes joked, calling them the five girls. (1.3.2)
Aw, Papi calls his wife and daughters his "five girls." Cute, right? Or maybe not so cute if we consider the incestuous vibe of the previous chapter.
Quote #6
The eldest, a child psychologist, admonished the mother in an autobiographical paper, "I Was There Too," by saying that the color system had weakened the four girls' identity differentiation abilities and made them forever unclear about personality boundaries. The eldest also intimated that the mother was a mild anal retentive personality. (1.3.5)
So this is the eldest daughter Carla's take on their parents' child-rearing techniques. Kinda harsh, don't you think? But maybe it explains why the family is still so close after all these years.
