Lala: socially awkward, dropped out of college after not getting an acceptance into the top Jewish sorority at her school, emphasis on social standing, has more Jewish physical features, lives at home and seems to do very little with herself
Sunny: intelligent, studying sociology at Wellesley college, more cheerful, ignorant to the prejudices faced by Jews, more “Aryan” facial features. We see the biggest character development through Sunny.
Peachy: rich and comes from old money, comes from a family with high social standing, highly concerned with his appearance, ashamed of his Jewishness, obnoxious and ignorant persona.
Joe: very proud of his Jewish heritage, kind and polite, doesn’t make much money, speaks Yiddish and celebrates on Jewish traditions in which the Freitag and Levys are ignorant or disdainful towards such as Passover.
Boo: concerned with social standing, lives her dreams through Lala, puts a lot of pressure on her, not supportive of her.
Reba: more laid back, allows Sunny more freedom, not concerned much with social standing.
