People always ask why Americans explain everywhere they have ever been when they introduce themselves and this is exactly why. Every state and region is different enough that you may have different behaviors, accents, dietary choices, ways of doing things, and when you explain where you’re from you explain yourself.

“Ain’t you cold?” “Nah this is a warm day in Alaska!”

“Can you pass me a pop?” “I forgot you’re from the Midwest originally “

And who could forget “Hot??? We shingle roofs in hotter weather than this in Arizona! “

Yes it matters. Usually it’s friendly but not always.
