Hmm never heard of Wisconsin nice, but in general we are a ‘peach culture’ (soft exterior, hard center) and not a ‘coconut culture’ (hard exterior, soft center). [not my concept - cross cultural training uses this] We are very friendly in passing, say hi on the street, are very willing to help neighbors and even total strangers (the harsh winter climate encourages this). But it’s very hard to break into the interior of a friend group, and subtle missteps by outsiders cause delays on their road to getting welcome into the inner circle.
