Sometimes I see American movies where people areas like Boston or something say 'I'm Irish'. Why? No you're not, you're American. Most Australians came from Ireland too, but we don't go around saying it like we just got off the boat.
a lot of americans with irish heritage are super proud of it for some reason, maybe because of the "struggle" their ancestors faced when they came to the US and all the shops had signs up that said "IRISH NEED NOT APPLY" or something, i dunno.
anyway if someone asks me my ancestry i say "irish." if someone asks me where i'm from i say "canada." if someone asks me my home i say "the US." if someone asks me where i live i say "switzerland." i'm all mixed up

Yeah, I hear that people with freckles only tan in their freckles. Like solar cells. Weird!
yeah that's me. my skin will burn and then turn white again but my freckles get 2x as dark.
