I created a thread but we had storms and computer went offline. I'll make my Concord and NH comments here. Most of the people were in Concord.
I come from ancient NH stock, early 1800s anyway. A great great great grandfather was pastor at the First Congregational Church for decades.
Unfortunately we moved in the 60s. Politics at my father's job, the usual mess. I know that after ten years there, my mother still had problems being accepted by the local folk because she was not a local gal.
After a transfer, my wife and I moved to between Manchester and Nashua in the early 00s.
We had an issue with one of the car's registration. I had to call DMV in Concord. I phoned probably ten times, and I think I got one live answer. The other times the phone just rang away, or it went into a
your call is very important to us VM, never to be returned.
As a part time writer, I submitted a piece to the Monitor. An editor told me I needed a local angle. I have lots of local angles, and supplied a few. He never returned another phone call, was always unavailable, just a rude SOB.
We noticed some vandalism at Blossom Hill Cemetery, where my Civil War veteran great great grandfather is buried, along with other family including my father. I reported it to the lady at the cemetery office. She suggested I file a police report. I waited a couple of years and then wrote a letter to Concord PD, after we'd moved again. A few months later I phoned to see if there were other vandalism reports, if there were arrests, etc. I talked to a gal and got not much info. I called back two or three times and left messages. Calls were never returned.
I worked in Merrimack. I've not seen this anywhere else I've lived, but at this business if you entered a room where two people were talking, neither would acknowledge you, not even to make eye contract. They would blow on, for five or ten minutes. Interruption was necessary if you wanted to speak. Is this normal New Hampshire or New England behavior?
Everywhere else I've lived, folks would usually break off to wave, say hi, or at least make eye contact and nod.
By the way, the social workers there didn't even know the proper nomenclature for their professional licensure. The social workers called themselves LCSW, although the licensure certificate states Licensed Independent Clinical Social Worker, same LICSW nomenclature as Mass. When I checked with the licensing board and corrected the folks at work, they were surprised.

Maybe that's why they didn't want to talk to anybody.
There's more, but it's late.
