What you all want to talk about? I could be the confused American asking questions across the sea.. lol..
Like.. what is moin or moin moin
I got a basic while in field of "Just our way in this region of saying hello / good day.. or replying to that.. but.. more of a local thing"
I can only think that compares to in the USA.. Some areas of the country would use "proper" english of a greeting like "Hello, Good Day to you" and in another place.. that could be replaced locally with "Hey Y'all"... or even.. "Wasssssssssup"
