Even if the police aren't after you, it doesn't matter. You can even pass as a legal person, but you know that you're not. It is psychological, that is, you feel afraid, and you don't feel like you're in your own country.
Al principio, lo que más uno siente, bueno al menos yo, me siento frustrada porque no soy legal, aunque no te moleste la policía, no importa, hasta puedes a lo mejor pasar como una persona legal, pero tú sabes que no lo eres.
