All sorts of strange people were around, people who looked more at home than she was, even the homeless ones who spoke no English, more at home maybe because they were younger, and when she went out it seemed to her that she too had migrated, that everyone migrates, even if we stay in the same houses our whole lives, because we can't help it. We are all migrants through time.
Lydia is constantly reminded that her education has no purchase here, that she has no access to the kind of information that has real currency on this journey. Among migrants, everyone knows more than she does. How do you find a coyote, make sure he's reputable, pay for your crossing, all without getting ripped off?
