I was on a business trip to Yorkshire once. We were staying in a hotel in Barnsley and my colleague parked his car. Just as he got out, two blokes walked by us and one of them punched him in the boat and walked away. No words had been exchanged: it was just a random act. For any southerners...
I always liked the description from, I think, golfer Mark James. "A Yorkshireman is like a Scot but without their sunny disposition and generosity of spirit"
