I had a friend who went to Aberdeen Uni in the 80s and had a girl in his class from Peterborough. Her mother had packed a whole case with toilet rolls, and was concerned that there might be no pavements...
Your point caller?
I think the caller's point is to illustrate (rather well) the kind of perception that people outwith the Highlands and the North have of "up here". I have certainly found it commonplace for Central Belters to have the delusion that people in, for instance, Aberdeen, Inverness and Thurso live in adjoining villages up in what they think of as "The North" (which sort of starts when they get to Castlecary Arches). I suspect there are also some who think we also hack the heather out of each other's ears with Claymores, occasionally foray into the South to steal cattle before returning home for the monthly Brigadoon reinactment.
(Now could you imagine us up here harbouring equivalently silly ideas about people in the South dressing up in white shell suits and burberry baseball caps and swigging Buckfast whilst spray painting bus shelters on their way to collect their Giros? )
Anyway, what I was getting round to saying was that a lot of central belt players will initially have a completely inaccurate perception of what it's like up here. Those who are brave enough to give it a try will find it completely different from and a lot better than what they expected but at the same time we can't get away from the fact that it's still a long way away frrom families etc for many of them to stay longer than a contract or two.
