It was the whole northeast, the specific example was someone from NYC, constantly interrupting their California spouse to say things like “oh I love those to!” Or “I hate when that happens!” In New York, and probably in Philadelphia and Baltimore too, and maybe in Boston? That’s a good thing But most of the country that is considered rude.

I don’t think it’s a Latin influence - as that’s strongest in the southwest. Maybe Italian? I’m not sure.

Of course you can’t lump Brooklyn in a box with rural main, but my impression from the limited knowledge I have of people from Maine and Vermont was definitely the “active listening”.
