It amuses me what's been true in the rest of the world (Vancouver, Sydney, Aukland and London come to mind but I'm sure it's not just the Anglosphere) for decades arrived in the US a couple of years ago and is suddenly a shocking new thing
Americentrism. America discovers that water is wet and suddenly out come the flags and eagles
That makes sense. Those other places don't actually matter, but America does.
Can't even understand whether you're being ironic or not.
They matter, but not like in the sense that Americans should care about them.
If something hasn't happened in your area before, it is new to the experiencer regardless of it having occurred elsewhere. If an area experiences a flash flood are you likewise amused by their exasperation at the novelty of their situation, despite it having occurred to plenty of other people in other places?
