North & South should get on better together as long as they remember the basic rules and courtesies.
Southerners: change your money for pigs & sheep at the Watford Gap border post. Chewing on a piece of straw will help you blend in better, as will wearing the appropriate clothing, eg rustic smocks, bailer twine instead of a belt. A ferret, flatcap and/or whippet make a useful accessory. If going out for the night, expose the maximum amount of flesh possible, particularly in January, and NEVER wear a coat.
Northerners: White stilleto heeled shoes are de rigeur south of Watford Gap. Bleached blond hair backcombed to the sky is essential, as is Burberry clothing. Talk in a very loud voice, cackle & shriek with laughter at nothing, and start every sentence with the word "bleedin'". Greetings include "awright my son" and "wotcha darlin." Have your taste buds surgically removed then eat jellied eels.
