Our reading
An editorial interpretation.
The speaker suggests that existence itself is unfamiliar territory, where everyone is a visitor without a native's ease. Customs, rules and meanings must be learned as we go, and belonging never quite arrives. The metaphor turns ordinary living into a long trip abroad, with all the wonder and disorientation that implies.
