True enough but he nails both Liverpool and Manchester perfectly in that book.
It's quite easy tbh.
When you live atwixt both Metropoli you tend to go to both for the 'yin' and it is easy to see the 'yan' as you ultimately draw comparisons between the 2 places. Things that are endemic/quirky to one of the places then stand out a mile.
Mancs will bag scousers for stuff that they perceive to be different, yet most young Mancs won't have even been to L'pool.

In both city's (and probably maj. of city's) the folk from outside are viewed as a bit thick or wet behind the ears, not streetwise if you like, yet I grew up wise of both city's and the differences feeling equally at home in either, whereas the young lad that hangs around on the corner in say Croxteth or Broughton may know 'his world' like the back of his hand but taken out of it and placed in the other they are as lost as if dropped into the desert, stand out like a sore thumb and probably more likely to be singled out by the locals.
