Tourists in a city rely on the people around them for information that websites and maps can't always provide — the local knowledge, the honest recommendation, the shortcut that saves twenty minutes. And those conversations happen in English, because it's the language that fills the gap between any two people who don't share a native tongue. This exercise builds the vocabulary for those moments: the words for describing places and getting there, for recommending and warning, for helping someone feel oriented in a place they don't know. You don't have to be in the tourism industry to need this vocabulary — you just have to live somewhere that visitors sometimes ask for help.
