Wearing your heart on your sleeve.

"Wearing your heart on your sleeve" was a symbol of praise or ridicule depending where you were born.
The North has always been seen to be a grass root constituency meaning that the people were on the whole poorer and therefore the effects of a poor economy and the implementation of political decisions are much more likely to be felt by the poor than by the middle class.
The further north you go the more likely the population is susceptible to the vagrancies of decisions made in the corridors of power.

One of the main driving forces of the Scotish revolution was their feeling of a disconnect between Westminster and the needs of Scotland. The binding force of Nationality meant that whilst the North of England felt equally left out they didn't see themselves as a unit, a common voice to speak for the man in the street.

Listening to the SNP is refreshing. Turning up en bloc to take their seats in Parliament they are generally hostile and very vocal in their opposition to the Government. The Labour Party are a shadow of what you would expect The Opposition to be having spent so much time sifting the policies of the Conservatives to oppose only what the Middle Class wouldn't find distasteful, they have lost the ideological base for being in true opposition to the Conservative Party.
"Southerners" have a different philosophy. The counties surrounding London feed from the economic Dynamo which the capital city generates and the population on the whole benefits economically. There is less of a tribal affinity other than the Cockney to the East of the City and this sense of individuality leads them to believe that they cope as an individual, irrespective of what the Establishment decrees. You often find, in discussion, a lack of compassion towards others less well off than themselves. The philosophy "if I can do it so can they" is well entrenched and little cognisance is taken of the circumstances that can throw a curved ball to anyone.
To wear your heart is to acknowledge you have one but of course I speak of the emotional, empathetic, heart not the muscle !!!
