I believe she doesn't come out because she is afraid to speak English, and maybe this is so since she only knows eight words. She knows to say: He not here for when the landlord comes, No speak English if anybody else comes, and Holy smokes. (30.6)
For Mamacita, foreignness is an isolating experience. Her inability to communicate with people in her community is the ultimate expression of her foreignness.
Quote 65
My father says when he came to this country he ate hamandeggs for three months. Breakfast, lunch and dinner. Hamandeggs. That was the only word he knew. He doesn't eat hamandeggs anymore. (30.7)
Esperanza's father can relate to Mamacita. His refusal to eat hamandeggs anymore can be read as his way of trying to forget the isolation he felt as an immigrant.
Quote 66
¡Ay! Mamacita, who does not belong, ever once in a while lets out a cry, hysterical, high, as if he had torn the only skinny thread that kept her alive, the only road out to that country. (30.15)
