Answer:
Anita is used to seeing people "fly" to another country to get freedom. When Chucha says she must "fly, fly free", she is saying that Anita should not be bound by a country that does not allow her to have what she wants, freedom.
Step-by-step explanation:
Chucha is a very special person for Anita's family, as she helped to create several members of that family. She sees Anita's willingness to have freedom in her home country and in her personal life. Anita, she is used to seeing her family members "flying" to other countries in search of freedom and in search of escape from dictatorial and authoritarian oppression. However, she wished it were not necessary.
Chucha tells Anita that now is the time to "Fly, fly free!" This thought shows how Chucha believes that it is not right to cling to a country that does not offer you the necessary freedom, so you should not miss the opportunities to " fly "(immigrate), when that opportunity is viable.
