If all one knows about the “north” is folks from NYC, Philly, and Boston, allow me to suggest that you know JACK about folks from the north.
There’s a lot of rural territory in them thar northern states, and the people are every bit as kind and decent as those from the rural areas in the south.
Can't be said enough. Folks in all rural areas have far more in common with each other than with urbanites and city folks.
It’s not a northern lack of courtesy. It’s a modern lack of courtesy.
You are right. As a native of the south I am compelled to agree with you.
