I will be honest and I don't think you'll be offended.
I went to New York with my wife at the end of September. I'd always wanted to visit since I was 13 or 14 and first started seeing movies like Tootsie, Saturday Night Fever and Manhattan and Annie Hall. In many ways it couldn't possibly live up to my high expectations.
But it did and then some. And the reason? The people. The friendliest people on the planet live in New York I'm convinced of this. If we were looking at our map trying to figure where we were going or which Subway line to get on people would approach us and offer to help. Approach us? That's something on the whole I don't think Brits would do. That's just one example of how altogether lovely New Yorkers are.
And funnily enough I was talking with a friend from Chicago who's over here for a year when I got back and she said New Yorkers are probably known for being the rudest Americans.
So if they're the rudest?
