By the mid-1970s, she had become involved in theater. She went on to write several plays, often using both English and Spanish and focusing on the experience of women at a cultural crossroads.
"My intention as a writer is to explore, in many different ways, our being here," Prida said in the Repertorio Espanol, profile. "Being from a different culture. Trying to fit in or not fit in. How other people see us, how we see ourselves."
Her plays included "Casa Propia," in which buying a home spotlights the differences between a Cuban woman and her husband; "Coser y Cantar" ("To Sew and To Sing"), a bilingual comedy about the inner cultural conflicts of a Hispanic woman; and "Botanica," which traces cultural and generational divides and connections among a Puerto Rican woman and her granddaughter.
"She believed that, really, the way to engage people and kind of help them think critically and change their mind about issues was to use humor," said Amaro, a friend of Prida's since 1977. "She felt that that's really the way that you capture people's attention and engage them in social analysis."
