I used to work with a guy whose parents were Pakistani but who had been born in Scotland, although he had quite a strong accent from living with his grandparents for several years. People used to ask him "So where are you really from?" quite often.

"I'm from Wishie", he'd say.

"No but where are you really from?"

"Well, dinna tell onyone," he'd say, dialling up the Lanarkshire accent, "but I'm really from Newmains, but if they hear I'm from there they'll think I'm a bam"
