Random thing about me. I lived in Minnesota from age 3 or so until 11 (basically the 80s). I absorbed a lot about being a Minnesotan at those impressionable ages, even if I don’t consider myself as ‘from Minnesota’ at all.
However, Minnesota Nice is a real thing and I have a sticky note on my monitor at work to remind me to be Minnesota Nice (complete with a crappy drawing of the state) when dealing with those customers that I really wish I could stab through the phone.
