I am a Yorkshireman - I hate mushy peas and Yorkshire Pudding but I do know someone who refuses to go outside Yorkshire for a holiday.
My first week or so in boarding school (I didn't have wealthy parents, I got a scholarship) I got into a fight over my strong Yorkshire accent. He got a bloody nose and I got a black eye and we were both hauled off to the head for a caning. We became best friends for the rest of our years in school.
My wife (Spanish, grew up in Paris) does still remind me from time to time that I'm a Yorksireman!
