The context is just her life. That she’s attempting to apply to everyone always. The problem is not the question like she seems to assume. And her solution to ask “Where do you consider home?” is awkward and doesn’t really help.

To note, the problem is the underlying assertion that they have to be from somewhere foreign when other people in the same area won’t have that assumption applied to them. So the context the question is asked in matters a lot and her blanket statement completely takes that context out of it.
