The American friend who should have paid attention in Geography class
It is reasonable for someone to be unaware of their country’s full history or even the names of all of its locations. After all, that is just way too much information, but this one, in particular, is excruciatingly terrible to hear.
Sure, they may not have visited Idaho or heard much about it, but it is impossible for them to have never heard of or come across that name in school. They seem to be the only Americans in the room.
