See this is a good one. I like how you consider yourself to be a Manc, but for me you're not one, you're a cockney.
A reverse of this is an example of a former friend of mine. He was born in Crumpsall, like me, and lived in Moston all his life until 18 when he went to Sandhurst Military College. He came home 2 times a year and even the first visit we could tell he'd changed to fit in with his twattish, elite-est friends. He no longer considered himself as from Manchester, instead he told his friends at College that he came from 'a little village on the Yorkshire/Lancashire boundaries'. The 'village' he was referring too was fucking Chadderton! He thought that if he said he was from Manchester he wouldn't be able to fit in with his home county, rich friends. We disowned him after that and the last we heard he was a cigar smoking, port drinking fanny of a man.
